Level up:

The Shadow Riders were not defeated yet. The Key Keepers were not even close, they had only defeated 5 of the Shadow Riders and there were still 7 left. And the sixth Shadow Rider was making his move, or rather her move.
In a small hideout in the Northern part of the forest, hidden from Academy was a wooden hut, our next Shadow Rider was hiding in this hut with ravens flying around the hut, and they were delivering messages to her. These ravens were like the bats that Camula used and the woman lowered the hood that he had which revealed a woman with short red hair and a sly smirk across her lips. 
"So my ravens have returned and now I can select my target and the Nightingale will strike." The woman said and she eyed the figure of a girl wearing a white and blue uniform with short hair like hers except it was brown and she had green eyes. 
"This will be the Nightingale's target." She added. "These Key Keepers may have defeated some of the Shadow Riders, but now we'll see how they fair when they go up to the next level." She said to one of her ravens as she looked at the sun which was rising in the distance. "It's time to hide for now but when night falls, we shall make our move."
...
Kallian Tabris was shocked that she had been promoted to Ra Yellow. She had dueled that Obelisk Blue bully because she wanted to teach him a lesson and show everyone that Slifer Reds could duel as well. She had won thanks to the Legendary Planet Monster, the Grand Jupiter, she had that card ever since she started dueling but rarely summoned him, as she feared that a snob duelist might try to claim it as a prize since it was a very rare card. Now she was no longer a Slifer Red any more, she had been promoted to Ra Yellow though she swore that she would still try to help the Slifer Reds when she could. Kallian stood outside the Ra Yellow Dorm and was now dressed in a yellow blazer and yellow skirt. Waiting for her were Theorn Maheriel, Neria Surana and Bastion Misawa, three Ra Yellows who Jaden Yuki considered friends.
"Hey Neria." Theorn greeted. "So you made it."
"Well this is quite a change for me." Kallian confessed, "I wasn't expecting to be promoted."
"Well congratulations." Bastion said. "The way you beat that Obelisk shows that you can duel and you put confidence into the Slifer Reds"
"Now at the Red dorm you had to bunk with someone." Neria added and Kallian nodded at her. "Well here you all have your own rooms."
"Well at least I won't have a prankster who pours water on me or sets my alarm volume really high." Kallian muttered to herself
"Professor Sartyr, head of the Ra Yellow Dorm asked me to escort you to your new assigned room." Neria added. "You have been granted Solona's old room before she was promoted to Obelisk Blue and it's right near our rooms."
"I'm sure you will be fine." Theorn stated. "And if you need help, just come and ask us."
Kallian smiled at them. 
'I guess I can get used to this.' She thought
...
The next day when it was time for class, the lesson was Dr Crowler's class and he was a bit worried, usually, he would pick Slifers to answer his harder questions to make them look like fools but Seto Kaiba had given him a warning and now Aristide Amell was keeping an eye on him and the Obelisk Blues to ensure that there was no bullying. Though some Obelisks thought that they could get away with it but they would find themselves in a lot of trouble and it had only been one day since Kallian's Duel with Torimaki and a few Obelisks had been personally escorted to detention by Laxus after the security cameras caught them mocking the Slifers.
Soon all of the students were in the Lecture Hall with the Obelisks sat at the top, the Ra Yellows including newly promoted Kallian and the Slifer Reds sat at the bottom. Crowler then sat at his desk when all of the students had sat down for class though like usual, Jaden was sleeping through the class.
"All right class." Crowler announced. "Our class today will be focused on Level Monsters. Can anyone tell me what a Level Monster Is?"
Chazz knew what these monsters were as he had used them before so he answered the question. "Level Monsters are series of monsters that have the same name but each monster has a different level. They all have similar abilities in that particular series and the higher the level, the more powerful its ability. An example is the Armed Dragons, Level 5 can destroy one monster on the field by discarding one monster with more attack points. Level 7's ability is by discarding a monster, all monsters with less attack points are destroyed and Level 10'a ability is the most powerful which is by discarding one card, all face up monsters on opponent's field are destroyed."
"Good answer." Crowler praised. "But how do you level up these monsters?"
Sereda answered that questioned. "Each type of Level Monster series is different. To level up Armed Dragon Level 5 to level 7, you must have level 5 destroy a monster in battle and then level up at the end. The effect is similar for Horus the Black Flame Dragon to level up from Level 6 to Level 8. The Silent Swordsmen and Silent Magician monsters are different. You summon the lower level monster and each turn, a counter is added which increases the level and the attack points until you can level up to the next level."
"Correct." Crowler said. "But there is a quicker way to level up the monsters, who can tell me what it is?"
Kallian remembered the answer and decided to show that she deserved the promotion she got. "There is a spell card called Level Up which allows you to level up the monster to the next level ignoring the summoning ability."
Crowler smiled at her answer and then Jaden yawned and managed to wake up and stretch his body. "Ah, I had a good nap. So what did we learn today?"
Syrus looked at him. "Jaden you really need to start paying attention otherwise you'll never pass the written exam."
"Listening to Crowler's lessons are boring though." Jaden complained
"Mr Yuki!" Crowler yelled at him which made Jaden and the students around him jump
"Uh yes Dr Crowler?" Jaden said quickly
"Chancellor Sheppard would like to see you in his office after class." Crowler said. "And he would like to see the following students. Chazz Princeton, Solona Amell, Daylen Amell, Sereda Aeducan, Neria Surana, Aedan Cousland and Alexis Rhodes."
Solona had a feeling that this might be about the next Shadow Rider.
...
Solona was right as Sheppard had important news for them in his office along with Professor Dorian. 
"There is a possibility that the next Shadow Rider is here." Sheppard said. "We had reports of strange sightings in the northern part of the Island."
"What kind of sightings?" Solona asked
"There had been reports of a strange woman in the Northern part of the island and when she lays eyes on you, she turns into a flock of ravens and then scatters, this could be the work of the Shadow Riders and it seems the next one has arrived."
"Do you know where this Shadow Rider could be hiding?" Sereda asked
Sheppard looked at Dorian who answered the question. "While I was patrolling the island I came across some kind of hut in the Northern Forest that could be where our Shadow Rider is."
"Well what are we waiting for, let's get going there." Jaden said cheerfully
"Jaden hold on." Aedan countered. "We must be careful, we've already lost four of the Spirit Gate keys and we cannot go rushing in recklessly."
"I agree." Alexis stated. "We'll all go to this hut with Dorian and then if our Shadow Rider is there then we will decide who duels."
"Or whoever that Shadow Rider picks will duel." Solona stated as she remembered that all of the Shadow Riders chose their opponents.
...
Later they followed Dorian into the Northern Forest. This part of the island was largely covered in thick forests and there were no signs of anyone living here. There were paths that went around the Forest but it was unwise to leave the paths, as it was easy to get lost. The Abandoned Dorm, the Gravekeeper Ruins and the Spirit Well were all located in the Northern forest but now Dorian was leading them to a strange hut he had found.
They searched for a long time and they always stuck together but they eventually found the hut but by then, the sun had set.
"So this must be the hut." Jaden spoke up
"It looks deserted." Alexis stated
"But we should be on our guard." Solona suggested, "We have no idea what lies here."
"She's right." Aedan agreed. "There could be a trap set here."
So all of the remaining Key Keepers and Professor Dorian searched the area around the Hut. They could not find anything until Sereda moved some branches on a bush and she jumped back in shock and fright as a flock of ravens flew out of the bush which knocked her down.
"Sereda, are you all right?" Solona asked her
"I'm fine Solona." Sereda answered. "That just took me by surprise."
Then they heard cawing and everyone watched as the ravens all cawed and circled around which made Neria frown. 
"Uh oh, this is like what happened before that Shadow Rider Blackbird showed up." She said
She was right as the birds flew in a tornado like way which formed a curtain and then the curtain cleared, there was a figure standing where the tornado had been. The figure was a woman who wore black robes with a hood covering her head though the Key Keepers could see auburn red hair under the hood. The woman also had a necklace around her neck which was in the shape of a raven.
"Who are you?" Aedan demanded
The woman laughed. 
"Shouldn't you know I'm one of the Shadow Riders." She said.
"Oh great, I knew that this must have been a Shadow Rider." Solona groaned
The woman laughed again. "You can call me Nightingale and I'm here for those Spirit Gate Keys."
"Well we're not giving them up without a fight!" Jaden shouted. "If you want a duel, then get your game on!"
Nightingale laugh. "Hold up, I choose who my opponent will be." She sneered and then she pointed at Sereda. "And I pick you as my opponent."
"Well I don't back down." Sereda hissed and she walked up. "If you want to duel me, then let's go"
The remaining Key Keepers looked at her. 
"Good luck Sereda" Aedan said to her.
Soon Sereda and Nightingale were on opposite sides of the area around the hut and they had their duel disks ready. 
"All right." Nightingale said. "Let's go over the rules, if you win then you keep your Spirit Gate Key and another Shadow Rider will be defeated." Nightingale smirked. "But if I win, then I get your Spirit Gate Key and your soul will be mine to add to my ravens and I will carry on to gather the remaining keys."
"Well I'm not going without a fight!" Sereda hissed. 
"Now let's go." Sereda and Nightingale activated their Duel Disks and Nightingales was like a raven's wing, similar to the disk that the Shadow Rider Blackbird used during his duels against Theorn and Solona.
"Duel!"
Sereda: 8000
Nightingale: 8000
"I'll make the first move." Nightingale sneered as she drew a sixth card. "And I'll start by playing the spell card Cost Down, now by discarding one card, all monsters in my hand lose 2 levels until the end of this turn. Which means I can now summon this without a sacrifice, Horus the Black Flame Dragon Level 6 in attack mode." A large winged dragon with bronze scales appeared on the field (Level 6 Attack 2300 Defense 1600) "And then I will play the spell Monster Reborn which allows me to summon back the monster I discarded, come on out Masked Knight Level 3." A small knight in white and yellow armor appeared on the field (Level 3 Attack 1500 Defense 800) "Even though I can't attack, my Masked Knight can still deal damage as if I don't attack with him, then you take 400 points of damage, now take out some of her Life Points." Masked Knight slashed his sword and caused some damage to Sereda.
Sereda: 7600
Nightingale: 8000
"Oh no, first turn and already Sereda is losing." Neria gasped
"Hey this duel has just started and I'm sure Sereda can pull through." Jaden commented
"I place one card face down and end my turn" Nightingale finished
"My turn." Sereda hissed as she drew her next card. "And I play the spell card Double Summon which allows me to summon two monsters this turn. So I will place one monster face down and summon Dwarven Soldier in attack mode." A short soldier dressed in armor appeared on the field wielding a large axe (Level 4 Attack 1600 Defense 1200) "Now Dwarven Soldier, attack that Masked Knight." Dwarven Solider charged at Masked Knight and slashed his axe and destroyed the knight.
Sereda: 7600
Nightingale: 7900
"Then I will place one card face down and end my turn." Sereda finished. 'Now the face down monster is Dwarven Scout, as soon as he is flipped, his effect will destroy one of those monsters and my face down is Barricade so it will stop an attack on my Soldier.'
Nightingale smirked. "If you think you have seen the last of my Masked Knight then you're wrong." She sneered. "I play my face down Call of the Haunted which allows me to summon back my Masked Knight." The Masked Knight returned to the field. "And now I draw." Nightingale drew her next card. "And now I will take this up to the next Level. In my standby phase, I can sacrifice my Level 3 Masked Knight and replace him with his Level 5 counterpart." Masked Knight Level 3 was engulfed in a bright light and when the light cleared, a larger version of Masked Knight was on the field (Level 5 Attack 2300 Defense 1300) "And then I will normal summon Mystic Swordsman Level 2 in attack mode" A small blue swordsman appeared on the field (Level 2 Attack 900 Defense 0)
"What good will that do?" Chazz wondered. "There's no way it can destroy Sereda's monsters"
"Well maybe it has some kind of special ability." Alexis questioned
"Well we will find out." Solona stated
"Now Horus, take out that Dwarven Soldier." Nightingale ordered and Horus swooped down onto the soldier.
However Sereda activated her trap. "I play my face down card, the trap card Barricade, now I can negate the attack on one of my Dwarven Monsters." Horus's attack was sent back to where it started
"Well I still have my Masked Knight." Nightingale sneered. "Now attack that Soldier instead." Masked Knight slashed Dwarven soldier and destroyed him.
Sereda: 6900
Nightingale: 7900
"And now, Mystic Swordsman, attack that face down monster." The small blue swordsman then went in for an attack. "Oh and there is another thing, when Mystic Swordsman attacks a face down monster, it is automatically destroyed."
"What!" Sereda gasped and the small sword slashed the face down card in half and no effect could be activated
"And now I will end my turn which allows me to Level Up my Swordsman to Level 4." Nightingale finished and then Mystic Swordsman grew into a larger swordsman (Level 4 Attack 1900 Defense 1600) "It's your move"
Sereda looked at her deck. 'I have to do something good, because I have a feeling that this Shadow Rider is going to keep upgrading her monsters.' She thought as she drew the card from her deck and she smiled at it. "I'll start by summoning Dwarven Smith in attack mode" A short dwarf wearing a Blacksmith apron and holding a hammer and axe appeared on the field (Level 4 Attack 1400 Defense 1400) "And when my Smith is on the field, all Dwarven Monsters gain 400 attack points" (DS Attack 1400-1800)
"But that is still not enough to destroy any of Nightingale's monsters!" Alexis spoke up
"What is she doing?" Neria question
"I think Sereda has a plan." Aedan said
"I sure do." Sereda smirked. "I play the equip spell Dwarven Longsword, now my Smith gains an extra 1000 attack points." The axe was replaced with a large sword made of bronze and gold colored metal ( DS Attack 1800-2800) "Now since I'm sure that Masked Knight will level up on your next turn, I'll attack that. Now Dwarven Smith, attack that Masked Knight Level 5." Dwarven Smith used his hammer and smashed the Masked Knight.
Sereda: 6900
Nightingale: 7400
"Then I will place one card face down and end my turn" Sereda finished
"My move." Nightingale sneered as she drew her card. "And I'll start by playing the spell Mystical Space Typhoon, this allows me to destroy that Dwarven Longsword." A large typhoon hit the Dwarven smith and blew his sword away causing his attack points to decrease (DS Attack 2800-1800) "And now my Horus will attack that Smith." Horus fired a fireball from his mouth which engulfed the Smiths and destroyed him.
Sereda: 6400
Nightingale: 7400
"And now my Mystic Swordsman will attack you directly" Nightingale added and then Mystic Swordsman drew his blade and the swung at Sereda but she had a trap.
"I play my face down card." Sereda announced, "Dwarven Spirit, now since you just attacked after destroying a Dwarven Monster, I can halve the damage I take from your next attack."
"Though you still take damage." Nightingale smirked as Sereda was thrown back when Mystic Swordsman slashed her with his blade causing her to be thrown onto her back.
Sereda: 5450
Nightingale: 7400
"SEREDA!" Aedan yelled
"I end my turn there." Nightingale finished. "And now the effect of Horus activates, since he destroyed a monster this turn, I can level him up to Level 8" Horus was engulfed in flames and was replaced by a much bigger one that stood on its back legs and had large arms that could smash a monster. The whole body was also on fire and the dragon had piercing black eyes and large wings (Level 8 Attack 3000 Defense 1800) "And if you plan to use any spell cards then forget it since my Horus can negate the effects of any spells while face up on the field." Nightingale sneered, "Now make your move"
Sereda sighed and she drew her card. 'This isn't going to be easy, the only monster I have that can beat that dragon is Dwarven Paragon but that card is still in my deck. And even if I summon a monster then I will get a direct attack. I guess I will have to play defensive for now.' Sereda thought as she drew her card. "I summon Dwarven Legionnaire in defense mode." A Dwarven soldier wearing black armor appeared on the field kneeling down (Level 4 Attack 1900 Defense 1500) "And then I will end my turn by placing one card face down."
"What is she doing?" Chazz gasped. "She'll be wide open for an attack with one of those monsters"
"I hope Sereda knows what she is doing." Alexis added
"I hope so too." Solona agreed
"That's it?" Nightingale laughed. "Well I guess you're not much of a challenge as I thought. Mystic Swordsman, attack that Dwarven Legionnaire." Mystic Swordsman swung his sword and destroyed the black armored soldier. "And now you are wide open. Unleash your might Horus, blast that girl and show her the nature of the Shadow Games." Horus threw his head back and then sent a blast of fire which exploded as soon as it hit Sereda."
"SEREDA!" the rest of the Key Keepers yelled and Nightingale sneered but it fell when the fire cleared and showed Sereda still on her feet and her life points hadn't changed
"What!" Nightingale gasped. "But how? Why are you still standing and why didn't you lose any life points"
"It's my Legionnaire's special ability." Sereda smirked. "When he is destroyed, I can reduce the damage I take to zero."
Nightingale narrowed her eyes. "I end my turn and now I can activate my Mystic Swordsman's special ability, now I can level him up to his highest level. I level him up to Level 6." Mystic Swordsman was engulfed in a large blue light and was replaced with a taller man wearing a white cloak and holding two large daggers (Level 6 Attack 2300 Defense 1700) "And he has a special ability, if he attacks a monster in face down defense, then that monster is sent to the top of your deck instead. Now make your move."
"Oh I will." Sereda hissed as she drew her next card. "I play my face down, call of the Haunted, now my Legionnaire returns to the field." the black armored soldier returned. "But he won't be around for long because I now sacrifice him to summon Dwarven Legionnaire Expert in attack mode." A much more heavier armored black soldier appeared on the field wielding a large hammer (Level 7 Attack 2700 Defence 2400)
"Wait that's a Level 7 monster so it needs 2 sacrifices." Alexis stated
"I can summon my Legionnaire expert with one sacrifice if I use Dwarven Legionnaire as the sacrifice." Sereda explained. "And now my Expert, attack that Mystic Swordsman." Dwarven Legionnaire expert swung his hammer and then slammed it onto Mystic Swordsman and crushed the monster.
Sereda: 5450
Nightingale: 7000
"That will do it for now." Sereda finished
Nightingale smirked. "You may have destroyed my Swordsman but my Horus is still on the field, now attack that soldier." She ordered and then Horus threw his head forwards and unleashed a blast of fire.
"My Expert can't be destroyed in battle so he remains on the field." Sereda smiled
"But you still take damage." Nightingale smirked and then Sereda was hit by a spark causing her to groan.
Sereda: 5150
Nightingale: 7000
"I end my turn there." Nightingale smiled
Sereda drew her card and she smiled at it. "I have more than one copy of my monsters." She smirked. "I summon another Dwarven Smith in attack mode." A new smith appeared on the field. "And don't forget, now all Dwarven monsters on my field gain 400 attack points." Dwarven Smith and Legionnaire Expert gains more power (DLE Attack 2700-3100 DS Attack 1400-1800) "Now my Legionnaire has enough attack points to destroy that Horus, so attack." Dwarven Legionnaire Expert swung his hammer again and slammed it into the dragon's head causing the dragon to groan before shattering.
Sereda: 5150
Nightingale: 6900
"And now you're wide open for an attack." Sereda smirked. "Now Smith attack her directly." Dwarven Smith swung his axe and hammer and threw Nightingale back a few feet.
Sereda: 5150
Nightingale: 5100
"All right!" Neria cheered. "Now Sereda has the strongest monster on the field"
"I will end my turn there." Sereda finished
Nightingale smirked. "You may have destroyed my Horus, but you have not won this Duel yet." She sneered and then she drew her card and smiled at it. "And if you think you have seen the last of my Horus then you are wrong, I play a spell card known as Level Modulation, now you draw two cards and I can summon any Level Monster in my graveyard ignoring the summoning requirements. And guess who is coming back." Sereda drew two cards and then just as she expected, Horus the Black Flame Dragon Level 8 returned to the field. "However since he was summoned with Modulation, he can't attack this turn or use his special ability, but I can still deal you damage with this, I play the spell card Level Strike, now I select one monster on my field and for each level it has, you take 300 points of damage. So since Horus is Level 8, you take 2400 points of damage." Eight small fireballs with a star inside appeared and they combined into one and then the Fireball was flung towards Sereda where she groaned and was thrown back by the damage.
Sereda: 2750
Nightingale: 5100
"Oh great, now she's just lost a good chunk of her life points." Chazz groaned
"Don't forget, Sereda still has the strongest monster on the field." Jaden replied.
"I end my turn by placing one card face down." Nightingale finished. "It's your move."
Sereda drew her next card. "I summon Dwarven Carta Rogue in attack mode." She said and a Dwarf wearing leather armor and wielding two daggers appeared on the field (Level 4 Attack 1600 Defense 1400) "And now I will attack, you may have brought back your Horus but my Expert still has more attack points." Dwarven Legionnaire expert swung his hammer.
"Sorry but I play my trap, Negate Attack." Nightingale sneered. "Now your attack is negated and your battle phase ends."
Sereda groaned. "I end my turn."
Nightingale sneered. "Now it's my move which means my Horus can attack, and I think I will choose to attack that Dwarven Smith so now your Expert won't have enough attack points to defeat my Horus." Horus threw his head back and sent a blast which destroyed Dwarven Smith and the explosion threw Sereda back.
Sereda: 1550
Nightingale: 5100
"I end my turn" Nightingale smiled
"It's my move." Sereda said weakly. "And I sacrifice Dwarven Carta Rogue to summon Dwarven Miner in defense mode." The rogue was replaced by a dwarf wearing miner's clothes and wielding a pickax (Level 5 Attack 2000 Defense 2100) "He may not be strong but he has an ability which allows me to go digging in my graveyard once per turn and recover any card in my grave and add it to my hand so now I will add Call of the Haunted to my hand. And I will end my turn by throwing two face downs and switching my Expert to defense mode." Two face down cards appeared and Expert then knelt down
"My move." Nightingale sneered. "And I will just have Horus destroy that Miner so you can't summon back any cards from your graveyard." Horus sent another blast and destroyed the miner. "Then I will end my turn"
"My move." Sereda hissed. "And I will play my face down card, Call of the Haunted which allows me to summon back my Smith." The smith returned to the field "And since he's back now my monsters gain the attack points which means that my Expert is strong enough again and I will switch them to attack mode. Now Expert, attack that Horus once again." Expert swung his hammer and destroyed Horus once again.
Sereda: 1550
Nightingale: 5000
"And now my smith will attack." Sereda added. "Take out some of her life points." Then Smith attacked Nightingale with his hammer and axe which knocked her back.
Sereda: 1550
Nightingale: 3200
"That will do it for this turn." Sereda finished
Nightingale narrowed her eyes at her. "You will pay for that!" She snarled. "I summon Silent Paladin in defense mode" A woman wearing silver armor and sword and shield appeared on the field (Level 4 Attack 500 Defense 1500) "And when she is summoned, I can add Silent Magician Level 4 to my hand. Now I will end my turn."
"Well that's not much." Sereda smirked. "I will have my Dwarven Smith attack your Paladin first." Smith hit Paladin with his axe and hammer and then the fairy monster screamed and shattered. "And now you're wide open for an attack, now attack her directly Expert." She added and Dwarven Legionnaire Expert swung his hammer and knocked Nightingale back, nearly destroying all of her life points.
Sereda: 1550
Nightingale: 100
"Oh right!" Jaden cheered. "One more attack and Sereda has defeated this Shadow Rider."
"Let's just hope that this Shadow Rider doesn't have any more tricks to use." Neria claimed
"I'm sure Sereda will be all right." Alexis suggested
"It's your move now." Sereda said
Nightingale narrowed her eyes at Sereda. "You may have defeated my Horus again, but this is not the end. I now summon Silent Magician Level 4 in attack mode." A young child magician apprentice appeared on the field with a childlike smile (Level 4 Attack 1000 Defense 1000)
"What good will that do?" Aedan questioned. "It hasn't got enough attack points to attack any of Sereda's monsters."
"And that Shadow Rider can't level her up to level 8 until she has 5 counters" Daylen added. "What is she up to?"
"I don't need any counters." Nightingale sneered. "I am levelling my Magician here and now with this spell." Nightingale revealed a spell card which made everyone gasp.
"NO!" Solona yelled in shock. "Not that card."
"Yes, it's Level up which allows me to Level Silent Magician up to Level 8 right now." Nightingale sneered and the Level 4 Magician was engulfed in a bright light and when the light cleared, the child apprentice was now fully grown had worn fancy mage robes. (Level 8 Attack 3500 Defense 1000) "And now I will attack your Dwarven smith and this attack will knock your life points straight down to zero." Sereda gasped in shock "Now Silent Magician, end this duel, destroy Dwarven Smith and the rest of her life points." Silent Magician swung her staff around and unleashed a large ball of light which was sent straight towards Dwarven Smith.
"Oh no!" Aedan gasped. "It's over, Sereda's life points can't survive this hit!"
"Sereda!" Solona yelled and then the ball of light hit Dwarven smith and exploded creating a large smoke field which covered Sereda.
"No Sereda!" the rest of the Key Keepers yelled while Nightingale sneered
"This duel is mine, your key and soul now belong to me." Nightingale sneered
"Not yet they don't!" A voice called and then the smoke cleared to show Sereda on her knees but she still had life points.
Sereda: 350
Nightingale: 100
"What but how?" Nightingale growled. "How did you survive that blast!"
"Take a look." Sereda smirked and everyone looked to see that she had activated a trap that she had placed on her field a while ago. "I played the trap card Dwarven Relief, now by taking 500 attack points from my Expert, Smith gained them so I was able to survive the blast." (DLE Attack 3100-2200)
Nightingale glared at her. 
"You may have survived that attack but you will not survive your next turn." She hissed. "So why don't you just accept it and surrender now."
"Never, I will never surrender, not while there's still a chance!" Sereda hissed back
Nightingale sneered at her. "Well make your move now."
"Oh I will and I will beat you!" Sereda growled in determination and she drew her card. "I play Pot of Greed which allows me to draw 2 new cards" Sereda drew two new cards and smiled at them, they were just the cards she needed. "I play a spell card known as Paragon Kal'Hirol the Dwarven Smith." She smiled. "Now by sacrificing my Expert and sending the top 5 cards of my deck to the graveyard, I can summon my Dwarven Steel Golem in attack mode." A large Golem made from steel and heavily armoured appeared on the field (Level 9 Attack 3000 Defence 3000)
Everyone looked in awe at Sereda's new monster but Nightingale laughed when she saw the attack points. 
"What a disappointment!" She sneered. "That Golem doesn't have enough attack points to destroy my Magician."
"Not yet he doesn't." Sereda smirked. "I still have one more card to play, I play the equip spell Dwarven Golem Crystals which gives my Steel Golem an extra 1000 attack points" large white crystals appeared on the Golem's arms and the Golem roared as he gained more power (DSG Attack 3000-4000)
"4000 attack points!" Nightingale gasped. "No you can't! I can't lose this duel!"
"Sorry Shadow Rider but this duel is over!" Sereda hissed. "Now Steel Golem, attack Silent Magician." She ordered and then Steel Golem threw a massive fist which hit Silent Magician and slammed the monster into the ground and created and explosion which caused small rocks to shower Nightingale and the shadow Rider screamed as she was thrown onto her back.
Sereda: 350 (Winner)
Nightingale: 0000
"All right!" Solona cheered. "She did it, Sereda beat another Shadow Rider!"
Sereda smiled and then she fell to her knees as Aedan caught her. 
"Are you all right?" Aedan asked her
"I'm a little tired out but I'll be okay." Sereda smiled
Then Alexis went over to the fallen Shadow Rider who had gone limp. Alexis wanted to see who this Shadow Rider really was, since she hadn't vanished like some it could mean that she was one of the missing students from the Abandoned Dorm. Alexis saw that the raven pendent had fallen and she picked it up and she realised that this was the Shadow Charm that this Shadow Rider held. Alexis lowered the hood and saw an older teenage girl with auburn red hair that went down to her shoulders.
"Who is that Alexis?" Daylen asked her
"It's the last of the missing students from that data." Alexis said to her. "It's Leliana, the last of the missing students, we need to get her to the infirmary."
Solona then took the fallen Shadow Charm from Alexis and looked at it. "Well we have defeated another Shadow Rider but that was a hard duel, and I have a feeling that we are just getting started, I think the Shadow Riders are going to get harder now."
Daylen and the other Key Keepers looked at her and they all had a feeling that she was right.
Duel!"
