Secret Revealed

As the fire flowed out of Arana's mouth, Lucy & the others could only watch in sheer shock & amazement. Who was Arana? How does she know Fire Dragon Slayer Magic? Was it even possible for two Dragon Slayers to even HAVE the same type of magic? These were the collective thoughts going through everyone's minds.
The flames seared the Gracio's face, causing the beast to drop Wendy as it covered its face in pain, letting out another loud roar. Wendy fell to the ground, Gajeel catching her before she hit. He placed her down on her feet to see if she could still stand.
"You alright kid?"
"Yes, I'm ok. But what about Arana?" Wendy asked still worrying about her friend.
"I don't think she needs our help." He replied as they looked at Arana facing off against the Gracio.
"Is she a Fire Dragon Slayer? Is it even possible for two Dragon Slayers with the same magic to exist?" Wendy asked Gajeel still thoroughly confused.
"I don't know. If it is I've never heard of it."
"Guys! Don't just stand there, I need your help!" Arana yelled at the two dragons as she avoided a punch from the huge monster.
Realizing the danger they were still in, the two rushed over to her. Gajeel looked at Arana suspiciously, "How do you know Dragon Slayer magic?" He asked curtly.
"I'll answer all your questions AFTER we kill this thing." Arana yelled back as the monster prepared for another attack.
"RAAGGGHHHH! DRAGONS!" It bellowed as it raced towards them.
"Okay you guys follow my lead." Arana looked at Gajeel & Wendy, both of them nodding their heads at her as they watched the monster approached, they gathered their magic once more. Gathering air in their cheeks.
"FIRE DRAGON…"
"IRON DRAGON…"
"SKY DRAGON…"
"ROAR!" they all called out at once as their respective elements shot out from their mouths. The attacks hit their mark, once again knocking the monster off balance. Arana teleported in front of the Gracio to get its attention, the monster swiped at her but she teleported again causing it to miss its mark and turn its back towards Wendy & Gajeel.
"Gajeel NOW!" Arana called, continuing to coordinate attacks.
Gajeel, now covered in his Iron Dragon Scales, rushed the beast, chop blocking on its legs causing it to stumble, but not fully fall over. Arana had a plan for that as well as she looked at Wendy who she teleported in the air with her, the two girls nodded as air began to circulate around the young Dragon.
"Sky Dragon's CLAW" Wendy spun around and kicked downward, sending a huge gust of wind towards her target, this finally caused the Gracio to finally lose its balance; falling on its back as Wendy gracefully landed on the ground. Arana clenched her left hand in a fist, diving head first towards the monster to land the finishing blow.
"Wendy!" She called. "Buff me up!"
Wendy slightly confused about how she knew of her other abilities complied holding her hands above her, "O strengthen of arm to cleave the heavens, ARMS!" a magic circle formed above Wendy's hands as Arana's right hand glowed red.
"Alright!" she said excited as she fell faster. "This will finish you off."
The Gracio roared, trying to stand but it was too late. Arana drew back her fist as flames engulfed it.
Everyone watched amazed once more, Gray sitting up as the girl fell from the sky.
"FIRE DRAGON…" Arana yelled angrily.
"She looks just like…" Gray began to speak.
"Natsu." Lucy said, not realizing she finished Gray's statement.
"IRON FIST!"
BAM!
Arana thrust her fist in the Gracio's face, the impact almost leveling the forest. Her comrades covered their eyes as dirt and dust flew towards them. The added enhancement from Wendy tripled Arana's already considerable power, easily decimating the already weakened monster.
Arana front flipped on to the ground next to the Gracio, with the monster finally beaten it began to disintegrate before their eyes. Arana stood at looked at the pile of ashes for a moment before collapsing to one knee in pain.
"Agh!" she winced holding her stomach. Wendy ran to her, propping her up.
"Are you ok?" the young dragon asked concerned.
Arana smiled weakly, "Yeah, I'm good. I'm just a bit out of practice with my Dragon Slayer magic so it takes a bit out of me."
Gajeel walked towards the two, grabbing Arana from Wendy and carrying her bridal style to the rest of the group, Wendy following close behind.
When they reached the others, Gajeel sat her down in front of the others. "I think it's time you told us who you are." Gray said to her with a stern tone.
"Back off Gray." Lucy scolded. "She's obviously worn out from the battle, let her rest a bit before we interrogate her."
"Don't worry Lucy it's fine." Arana smiled at her before looking at the horizon the sun was beginning to set. "We should head back to town, I'll tell you everything there."
Everyone nodded, Gray still looked a bit irritated. "Fine." He said curtly.
The others stood up and began to walk. Gajeel extended his hand to Arana, but she waved it off. "Don't worry I'm fine." She got up, albeit sluggishly and followed the others. She looked to the horizon and let herself get lost in thought.
Mom, Dad, Wendy am I doing the right thing? 
…
When they reached Oshibana, the group used a part of the job money to rent a room at a local inn. they rented two rooms, one for the boys and the other for the girls. After they dressed their wounds from the battle with the Gracio, everyone gathered in the boy's room to hear Arana's story.
Much to everyone's surprise, Loke was still present among them.
"Don't you have to go back to the Celestial World soon Loke?" Levy asked.
Loke smirked, "You guys forget I was able to stay in the human world for quite a while before having to go back."
"Besides, I felt that he should be here to listen too since he knew of the monster like Arana did." Lucy interjected.
"Oh, ok then." Levy shrugged.
The group sat down in the medium sized room, some on beds and a couple on chairs. Arana sat on a chair a small distance away from the group so they could all her speak. It was uncomfortably quiet for a few moments, Arana didn't really know what to say to them, she still had reservations on if she should tell them at all.
"Well are you going to tell us or not?" Gray asked irritated.
"Calm down Gray." Lucy once again scolding him. "Take your time Arana, whenever you're ready." Lucy smiled at the girl. Noticing what she had just said, Arana used that sentence as her starting point.
She smiled back, "Thank you Lucy. I guess for starters I should tell you guys my name isn't Arana."
Gray was unimpressed at the reveal, "Ok then what is it?"
"My real name is Aura Robin Dragneel."
The room fell deathly quiet, no one had any idea how to react to what they had just heard. Lucy spoke up first. "Dragneel…does that mean you're related to Natsu?"
Aura nodded, "Yes."
"Are you like his sister?" Levy asked trying to understand the situation.
Aura shook her head. "No, I'm his daughter."
"WHAAAAT?!" everyone else yelled in unison.
"Whose your mom?!" Gray asked now interested.
"Huh?" Aura looked him confused. She blinked twice her eyes wide, then answered as if her lineage was common knowledge, "My mother is Erza Scarlet."
Everyone looked at each other before looking back at Aura in sheer surprise, "WHHHHAAAATTT?!" they once again yelled in unison.
"N…N…Natsu & Erza…have a kid?!" Lucy asked still completely confused.
Wendy covered her mouth in shock.
"How is that even possible?!" Gray asked. "You're like 18 years old and Erza just turned 20!"
Aura placed her index under chin in a thinking pose, "Oh yeah, it was mom's birthday the other day."
"Answer the question!" Gray yelled trying to get her to focus.
"Oh sorry, my bad ha-ha." She smiled wide showing her teeth as she scratched behind her head.
"Well she certainly acts similar to Natsu." Juvia commented.
Aura's face returned to its serious look. "I'm from the future."
Everyone eyes once again widened in shock at this outrageous reveal, all with the exception of Gajeel, who still remained slightly unconvinced.
"Okay so if you're supposed to be from the future, why are you here?" Gajeel asked.
Aura looked pensively at the ground as she thought of her next answer, she knew if she spoke these next words that there was no turning back. That the future may be irreversibly altered, she was warned against this course of action, but she strengthened her resolve and spoke.
She looked at the group, her eyes filled with a combination of anger, determination, & fear. "There is an event coming, one that threatens to destroy Fairy Tail and the entire kingdom of Fiore." Her eyes looked cold at her friends, mimicking a look that her so called "mother" Erza would give.
Everyone's eyes opened in disbelief they had no idea how to react, Gray, Gajeel, & Loke wanted to call out Aura's omen as a lie, but the look in her eyes deterred that course of action. The girls on the other hand took initiative.
"Are you serious?" Lucy asked in disbelief, "I mean I'm grateful that you saved us from that-" she tried to think of the name of the monster they just fought.
"Gracio." Aura helped her remember.
"Yeah the Gracio, but you being a Dragon Slayer, coming from the future, and claiming to be the daughter of NATSU & ERZA. I mean it seems a bit outrageous, even for us."
Aura sat back in her chair and smirked, "I know it's a lot of info to process, but I'm telling the truth here." Aura stood from her chair and turned her back to the group, all of them looked at her confused unsure of what she was planning to do.
She slowly pulled her shirt up, just enough so the other could see her lower back. The sight horrified the group as they gazed upon it, cuts and lacerations decorated Arana's back leaving behind cringe worthy scars. The part that she wanted them to look at was in the lower right corner of her back. It was a burn, a severe one at that, but a faint mark could be seen on it.
"What is that?" Levy inquired.
"That's where my Fairy Tail guild mark used to be." She said as she pulled her shirt back down and reset herself in her chair. "And if you still have trouble believing my story I also have this." She rolled up her left sleeve and revealed a mark on her forearm. It showed a pair of axes, a sword covering where the handles crossed and what looked like a dragon circling around the three weapons.
"What is this?" Levy asked confused.
"It'-"
"It's a mating brand." Gajeel answered cutting Aura off.
"A mating brand?" Lucy asked still confused
"It's a mark that only appears when a Dragon Slayer has chosen a mate. It appears on the Dragon Slayer, their mate, and their children. It's sort of like a family crest. Each brand is different depending on the pair." Gajeel then pointed at the mark, "Don't those weapons look familiar?"
Levy got in closer and grabbed Aura's forearm as she inspected the brand. Her eyes opened in surprise, "Gajeel's right, these weapons look just like Erza's Black Wing Axes as well as her Flame Empress Sword." She gave Aura her forearm back.
"But Natsu & Erza don't have that brand." Gray interjected.
Aura rolled her sleeve down and took her seat. "Not yet, but the mark will appear on my parents shoulders in a few days." The serious look returned to Aura's face.
Again the room fell speechless. Lucy broke the silence as she regained her composure and spoke.
"Well I still-"Lucy began but Loke cut her off.
"I think we should hear her out." He looked serious.
"But Loke-" Levy began
"You saw the marks on her back, the brand on her arm, plus she knows about the Gracio. Only Celestial Spirits and a select few wizards in the world know about it."
"I agree, we should listen to what she has to say." Wendy got up and looked at her friends, "Ara- I mean Aura, doesn't seem the type to lie about something like this."
As they watch the determined look in the young girl's eyes, the rest of the group relented.
"Well since I'm still having trouble believing you're Natsu & Erza's daughter, why don't you tell us where you came from." Gray said laying on his arms on the bed.
Aura looked nervous, "Are you sure? I could mess up the timeline, my being here is already a huge gamble."
She looked at her newfound friends all of them either smiling or smirking at her.
"We don't mind, I love to hear stories about people's past." Lucy replied warmly.
Wendy & Levy nodded in reply to Lucy.
"I must admit I am curious about where you came from as well." Juvia added.
"Besides it's not like we don't break things all the time." Gray smirked.
Aura nodded and smiled, "Okay then, I'll tell you guys my story." Aura positioned herself comfortably in her chair as the Fairy Tail wizards watched her, awaiting for the young girls surely outrageous story. The girls and Loke looked on with anticipation, while Gray & Gajeel sat in suspicion.
Aura moved her hand to her mouth and cleared her throat, the brilliant night sky setting the scene for a tale of life and death, of highs and lows, but more prevalent the pain of losing family. Aura made sure she was ready mentally before speaking, "Okay, let me start from the beginning."
