Brain Unglaus

Brain Unglaus (ブレイン・アングラウス) was a mercenary turned warrior of the Re-Estize Kingdom. Although initially somewhat arrogant, after barely surviving an encounter with Nazarick's denizens, he was set on a path to becoming a far humbler man.
==Appearance==
Brain Unglaus had brown eyes with blue hair and the appearance of a wild beast. He was equipped with chainmail and wore a necklace and ring, which were infused with protection magic. His whole body was lean and his muscles were tough as steel and tempered through experience.
==Personality==
When first introduced, Brain was shown to be arrogant and supremely confident in his skills. Part of this stemmed from his incredible talent with the sword. As he was so exceptional that he was able to match Gazef Stronoff with very little preparation or training, he was convinced that since he had trained hard and obsessively to best his rival, there was no way he could lose to anyone. In his pursuit of becoming the strongest, Brain decided to abandon everything, except his dedication for the sword, and that anything was right as long as it would help him to defeat his rival. During this time, Brain was depicted to be somewhat amoral. While it was never shown or stated that he engaged in the more unsavory activities of the Death Spreading Brigade, he also didn't object to the horrible acts they perpetrated, such as murder, slavery, and assaulting women.
His personality changed drastically after having a run-in with Shalltear. At first, Brain was confident in victory until Shalltear was able to not only avoid getting injured by his strongest technique, but managed to catch his sword with virtually no effort. While this terrified Brain, he demonstrated enough conviction and bravery to face her. However, it was after that point (along with some emasculating taunting from Shalltear) that he began to show a somewhat cowardly side to himself, as his first instinct after Shalltear caught his sword was to run. Soon after, when Shalltear was able to toy with him, his shock and fear became pure terror and he fled from her with all of his might. Furthermore, he abandoned his underlings in the Death Spreading Brigade and escaped by himself, showing that he had been reduced to a complete coward with no thought or care given to them. Having his confidence completely crushed and getting a feel of what true terror was like, his attitude changed to one where he was completely depressed, hinting at a suicidal tendency. His talk with Gazef in his horrible state about how weak they were in the face of real power showed he had given in completely to despair and believed his life had no value at all. Gazef's inner monologue about how vast the world was and how obvious it should be that humans are weak indicated that Brain was so consumed by his desire to best Gazef and become the greatest swordsman that he never really took into account how big the world really was and that his devotion to his goal was naive and childish.
He eventually made a complete overhaul after meeting Climb and Sebas Tian. Seeing how Sabas used his great power to protect others, along with his polite and respectful attitude, left a deep impression on Brain. After he saw how Climb was able to withstand killing intent that left Brain helpless, he learned what Climb had what he lacked and decided to take up the things he thought he didn't need, such as friendship and honor. He changed to a much friendlier person who started to think that strength was more than simply being skilled with a sword. His newfound spiritual strength allowed him to face Shalltear again, this time without succumbing to his fear, and allowed him to cut through her fingernail that he couldn't even damage before. He also became grateful to Gazef and the two developed a deep friendship.
==Background ==
Originally a farmer, Brain was gifted with what could only be described as a god-given talent in the mastery of the sword. He always believed himself to be the strongest fighter inside the Kingdom, having never lost a fight before he entered the grand tournament to decide the King's guard captain. He easily fought his way to the final, where he faced off against Gazef Stronoff. A grand and close battle ensued between the two, but eventually, he would taste his first defeat at the hand of Gazef.
His win-streak was shattered and his confidence as an unbeatable warrior took a hit. He then decided to do everything he could to become stronger, so he would truly become unbeatable. While he received many offers from nobles, he declined them and went on a journey to improve himself, meeting various people such as Rigrit Bers Caurau. At the same time, in order to make a living, he started working as a mercenary for the Death Spreading Brigade.
After Gazef Stronoff had passed away in battle, Brain later take ownership over the former's residence. It became a place where he started adopting specific orphan children under him to train them as the next successor after Gazef.
==Chronology==
===The Bloody Valkyrie Arc===
When the hideout of the Death Spreading Brigade was being attacked, Brain confronted Shalltear Bloodfallen and tried to defeat her, but suffered a devastating defeat, failing to even scratch her. His absolute confidence was shattered by the immense difference of power between him and the vampire. He fled crying, escaping the massacre through a hidden tunnel.Overlord Volume 03 Chapter 2: True Vampire
===The Men in the Kingdom Arc===
 and The Men in the Kingdom II Arc
Brain retreated to the capital city of the Re-Estize Kingdom in order to hide from Shalltear. Gazef found Brain slumped on the side of a street and brought him back to his place.Overlord Volume 05 Prologue Brain was still shaken by his momentous defeat and used his time to recuperate. Whilst walking through the streets, Brain overheard a commotion and discovered Sebas Tian as he incapacitated the men who were attacking a young boy. He followed Sebas and Climb into an alleyway, where he saw Sebas release an extreme amount of killing intent, directed at himself and Climb. This was Climb's requested training under Sebas. After the bloodlust ended, Brain revealed himself and conversed with Sebas and Climb before fighting off a group of assassins who were also following Sebas.Overlord Volume 05 Chapter 4: Congregated Men
After defeating the assassins, Brain, Climb, and Sebas traveled to the brothel where Tuare was discovered. They attacked the brothel and captured Succulent, one of the members of Six Arms, and a member of Eight Fingers, Cocco Doll, leader of the slave trade department. Following the battle, Brain went back to rest at Gazef's house and they discussed the events and his defeat at the hands of Shalltear.Overlord Volume 05 Chapter 5: Extinguished, soared sparks of fire
Later, Brain was sent to partake in another raid on the Eight Finger's hideouts alongside Climb. He briefly talked with Gagaran of the Blue Roses before beginning the operation.
Overlord Volume 06 Chapter 7: Attack Preparations When they began, they had a scout infiltrate the compound they were to attack, with the scout discovering that all of the remaining Six Arms members were within the compound, along with a captured girl. As they were about to fall back, they met Sebas, who came to rescue the girl, Tuare.
Brain, Lockmeier, and Climb all infiltrated the back of the compound in order to rescue Tuare while Sebas dealt with Six Arms. The trio used invisibility to infiltrate the compound and broke Tuare out of her cell. As they were escaping, they were ambushed by Zero, the leader of Six Arms, and were forced to fight. At the same time, they discovered that the Tuare, they rescued from the cell was actually Succulent in disguise. During the encounter, Lockmeier and Climb were forced to fight Succulent while Brain fought with Zero. Climb and Lockmeier defeated Succulent and, as the battle between Zero and Brain was almost finished, Sebas appeared and defeated Zero with ease. Brain, Climb, and Lockmyer all left the building, only to witness a wall of fire off in the distance, which they thought was another one of the hideouts being raided.Overlord Volume 06 Chapter 8: Six Arms
During the battle, he, Climb, and Lockmeier were inside the wall of fire and they learned that people were missing from their homes. During their search, he spoted Shalltear and recognized her despite the disguise she was wearing. Knowing that they would all be dead if the vampire found them, he decided to act as a decoy, so he left Climb and Lockmeier. He fought Shalltear and used "Nail Clipper" - a technique combined of Fourfold Slash of Light, Field, and God Flash - to cut her fingernail. This pleased him greatly and he left jubilant. Shalltear pursued him, but stopped after seeing the two other people Brain was heading towards.Overlord Volume 06 Chapter 11: The Final Battle of the Disturbance
===The Magic Caster of Destroy Arc ===
Brain was present during the massacre at Katze Plains along with Climb and Gazef. When Gazef challenged Ainz to a one-on-one duel, Brain protested it, but Gazef convinced him to back down and be a witness to it. He watched Gazef die after getting struck by an instant death spell. Ainz allowed him and Climb to take the body, which Brain carried on his back.Overlord Volume 09 Chapter 4: Massacre
Later, in E-Rantel, Brain wondered why Gazef did not run away and expressed sadness over his death. He vowed to surpass Gazef and asked Climb to get a drink with him.
Overlord Volume 09 Epilogue
===The Ruler of Conspiracy Arc===
It was mentioned by Princess Renner that Brain was searching for a new replacement for Gazef Stronoff in the Royal Capital and planned to train the replacement to become the next Warrior Captain.
Overlord Volume 10 Chapter 2: Re-Estize Kingdom
===The Witch of the Falling Kingdom Arc===
It was revealed that Brain was appointed as one of Renner's guards outside the throne room where the meeting between King Ramposa III and Albedo had transpired. After the meeting was over, he and Climb, both of whom were waiting outside the room, were later ordered by Renner to go to her room while she went off with Zanac to have a meeting with Ramposa.
After finishing his duty under Renner, Brain apparently appeared to be training ten orphan children under his tutelage as future swordsmen. Particularly, Brain had taken those who he had believed to have some sort of potential, allowed them to live with him, and was training them in the art of swordsmanship. Once they had done their usual training, he allowd them some break time and then dismissed them afterward.
With that matter taken care of, he met up with two members of the Six Great Disciples. In the past, he opted those two from that group other than himself to train the children further and harsher. Even though Brain hadn't paid them much to do the job of training the orphans, they still took the time to teach the children anyways.
Suspicious of what the Sorcerer King was plotting behind the scene, Brain had made it his plan to get his students out of the kingdom alive as soon as possible. With permission from Vesture Kloff Di Laufen, Brain agreed to take one disciple under him alongside the children, hoping to have that person oversee their training and upholding their traditional swordsmanship techniques after escaping.
Later, Brain resumed training with his students after their break time came to an end.Overlord Volume 14 Chapter 2: The Beginning of the End
While the capital Re-Estize was already surrounded by the Sorcerer Kingdom's forces, Brain, Climb, and Renner were informed by the few remaining knights that Blue Roses was waiting for them after they had returned to the palace. To ensure Renner's escape to safety, Brain and Climb had conversed in secrecy of arranging a carriage outside of the palace. Since the maids weren’t there, the duty to prepare and procure tea then fell on Brain before they met up with Blue Roses. Brain left the room to guide Tina to where the water was boiled, as well as look for desserts to pair with the tea, ignorant of the remaining Blue Roses members except Lakyus plotting to drug their leader. Alongside Tina, he returned to the room with some trays of desserts. Before heading off to confront the Sorcerer King in single combat, he decided to bid his last farewell to the members of Blue Roses, Renner, and Climb. At the same time, Brain handed back Gazef's sword and the Re-Estize Kingdom's National Treasure, Razor Edge, to Climb, as he had no intention of carrying his late rival's will.
Strolling the streets of the Royal Capital, he was lost in thought on his plans of how to deal with the Sorcerer King alone. However, before he could think any further, Brain was confront by a powerful foe who arrived at his vicinity. Seeing how this unknown entity was trampling the streets where he used to walk with Gazef, Climb, and Sebas, Brain no longer cared about fighting the Sorcerer King. Enraged at this new foe before him, he decided to challenge the entity to a fight to the death, as it was responsible for soiling his precious memories. Brain raised his katana at the entity, who, likewise, drew his own blade, accepting his challenge and introducing himself as Cocytus. The sight of the opponent honoring him with a duel as a fellow warrior overwhelmed Brain with joy. Now aiming to prove his worth as a warrior, Brain placed all his skill and hopes on his ultimate attack, True Nail Clipper. Just as he was aiming at Cocytus's wrist, the other warrior, taking the first move, closed the distance between the two. Brain, holding out until the last second, waited for the other warrior to come into range and ultimately was slain by Cocytus. Despite losing, Brain's resolve and warrior spirit earned him Cocytus' respect. Brain's katana was claimed as a trophy while his body was taken to be preserved by the Frost Virgins.Overlord Volume 14 Chapter 4: Well-Prepared Traps
===The Half Elf God-kin Arc===
Upon learning of the Sorcerer Kingdom's invasion of the Re-Estize Kingdom, Unglaus's name was brought up by the Six Cardinals and, while some had an inkling of his full name, they knew him to be Gazef Stronoff's successor and talent. Some drew questions if they should extract Brain from the Kingdom, though Berenice Nagua Santini voiced her opinion that the warrior was not the type of man to retreat from a battle and would not be grateful for the Theocracy's intervention.Overlord Volume 15 Prologue
===Mass for the Dead Arc===
After the Catastrophe, Brain was in the Royal Capital working as a mercenary due to the dangerous times. There he comes across members of Blue Roses at a bar and swapped stories with them.
Memory of Chaos: Gagaran His presence was alerted to Gazef Stronoff by Climb. As the Kingdom was short-handed due to the ongoing, Gazef asked his rival to aid his nation. The mercenary seeing his long-time rival was serious agreed to help, but on the condition the Warrior Captain would duel him. Gazef accepted the terms, though their duel would have to wait as the time was not appropriate.
Memory of Chaos: Gazef StronoffMemory of Chaos: Climb Brain then traveled to E-Rantel to reinforce the city for the Tripartite Alliance against the Chaos Beasts and was assigned to a special unit.Memory of Chaos: Brain Unglaus 
After the summit of the Tripartite Alliance, Brain was still waiting for the promised duel with Gazef. However that had to be delayed as Gazef was needed to lead a force to investigate a site where Chaos Beasts in the north were emerging. Before the Warrior Captain left Brain made him promise to return safe. However it became soon apparent to Brain that something was wrong when Gazef never returned, and two adventurer teams were dispatched to the location where the Warrior Captain was headed. The mercenary followed the adventurers to the Northern Cave where he proved vital in helping defeat two Spear Chaos Beasts guarding the entrance of the cave.Mass for the Dead Chapter 08: The Lost Hero He remained there at the entrance with Blue Roses guarding it while the protagonist and his team retrieved Gazef.Mass for the Dead Chapter 09: Evil Darkness
When Gazef was rescued, it became clear to the royal family that their champion was unfit for duty due to being turned into a Contaminated Beast. Brain then became Gazef's replacement at Lakyus Alvein Dale Aindra convincing. Now under the command of Princess Renner, he was granted the use of Razor Edge until Gazef could be cured.Mass for the Dead Chapter 10: Crumbling Overture Late after the city was attacked by Jaldabaoth, Brain was one of the few human defenders that rose to fight the demon and his horde. He fought alongside Climb and would witness the protagonist save the city.Mass for the Dead Chapter 11: Demon Emperor's Feast
A few weeks after the attack by Jaldabaoth, Brain met the protagonist and Surako with Climb and Blue Roses in the city square of E-Rantel to thank the adamantite adventurer for organizing the adventurer tournament. The mercenary noticed that Soi was absent from the party, and was informed that she was making preparations at the request of Pluton Ainzach.
Mass for the Dead Special Event: (Part 1) Undercover Adventurer Brain watching the tournament with Climb witnessed the staff fight abilities and sword techniques of
Shall and Ku. Eager to test out their abilities, particularly Ku, as they both wielded similar weapons he volunteered to fight and fought them. Even though he defeated them and forced them to concede, he was interested that Ku was able to notice his instant sword flash technique and avoided. For his participation he received some chocolate confections which he gave to Climb to give to the princess.Mass for the Dead Special Event: (Part 2) Undercover Adventurer
For E-Rantel's Harvest Festival, Brain assisted in patrolling the streets during the festivities. At the same time he tried to help Climb find a gift for Renner. During the mock battle demonstration, Brain suggested that Climb participate to win the Longevity Nut, but his junior declined as he did not believe he could beat Aura and Mare.Mass for the Dead Special Event: E-Rantel's Harvest Festival
In the midst of several Cracks being formed in E-Rangel, releasing countless Chaos Beasts, Brain joined together with Climb and Lockmeier to complete a mission from Princess Renner to deliver Razor Edge to a specific location. The trio did their best to stay alive and avoid the roaming invaders in the city, but they were attacked by a pair of Giant Flying Chaos Beasts. To buy time for his comrades to escape Lockmeier sacrificed himself to distract the monsters.
Brain and Climb finally arrive at their destination, the E-Rantel Magic Research Institute. There they were greeted by the sight of not only the protagonist and his friends but a semi-cured and enhanced Gazef Stronoff fighting a Spear Chaos Beast. To aid in the revived Warrior Captain in defeating the monster, Brain tossed him Razor Edge. But before Gazef can land the final blow on his enemy, a series of Cracks exploded within the facility in the vicinity, bringing forth a dangerous entity.Mass for the Dead Chapter 15: Crackling World
Some months after the attack on E-Rantel, Brain was reported to be among the missing. In truth he was transported on the "other side" of the Crack. Due to the environment, he fell conscious but was alive. His body along with King Ramposa III was found by a wandering Gazef Stronoff, who then took them to safety by escaping through a Crack and back to the Kingdom.Mass for the Dead Chapter 16: Name of God
One back in E-Rantel, Brain recovered and joined Gazef's Four Kingdoms Rescue Team to liberate the people trapped on the "other side". Donning adaptive equipment, fighting beside Gazef, and noted that the Warrior Captain had become even stronger due to the side effects of being cured from contamination. The mercenary protected Gazef's back as the latter slaughtered a horde of Chaos Beasts that threatened the rescue operation. After seeing Sebas acting as a spearhead to break through the Chaos Beasts to allow the army to escape back through the Crack, Brain praised the old man's skill, despite Sebas trying to downplay it.Mass for the Dead Chapter 17: Eve of the Storm
Later the rescue team rushed back to E-Rantel after receiving word from the Sorcerer Kingdom that enormous amounts of miasma were spilling in from Cracks in every major city in the Tripartite Alliance. Since their unit was the only military force in the area, the joint international force hurried to the alliance's capital to save what they could.
When they reached the territory of E-Rantel, Brain reported to Gazef that the adventurers spotted a horde of feral humans, most likely having turned into Contaminated Beasts after inhaling the miasma. After the team reached the city, Brain remarked on the dire situation of the city and asked Gazef what their plan would be. Later when plans were made to have separate teams go into the city and save those who still retained their sanity, Brain was astonished that Gazef would be going in alone. Though this was due to the Warrior Captain being immune to the miasma thus its effect on his was negligible. Brain was frustrated that he could not fight alongside Gazef due to the Warrior's Captain's advantage and focused on fighting the feral demi-humans to open a path for his allies.Mass for the Dead Chapter 18: Salvation of Mankind 
==Abilities and Powers==
Brain was a Genius/Fighter class compared to most other melee-oriented combatants who have the Fighter class as their starting class. While most learn martial arts that have been passed down through the ages, Brain developed his own unique martial arts.
In the Web Novel, when he lost his humanity to Shalltear and got turned into a Vampire, Brain would later step into the Realm of Heroes in terms of total levels thereafter. According to Maruyama, Gazef Stronoff cannot win against someone of that level anymore. However, it does not mean that there are no prospects for victory for Gazef.ARCADIA 2.29: ARCADIA 2878
At the time of his death, he had surpassed Gazef and reached the Realm of Heroes. Cocytus also estimated that the warrior's level was around 40 when he used his True Nail Clipper.

==Relationships==
===Gazef Stronoff===
Brain used to see Gazef as his nemesis and rival due to his defeat at the hands of the Kingdom's Strongest Warrior, wishing to overcome him to prove that he was the strongest. By the time he met Shalltear, Brain thought that he was ready to confront Gazef and believed that when the two meet each other, they would have a duel to the death. 
However, that all changed right after having his self-confidence and willpower crushed by Shalltear Bloodfallen. Unlike how they've met each other during their match together at the tournament, Brain confronted Gazef yet again, but this time, he was a shadow of his past self. Brain had almost prompted himself to even think of wanting to commit suicide before Gazef stepped in to stop him from thinking that way. Brain would later respect Gazef for his action and appreciated his kindness for helping him out in his time of need. 
He was greatly saddened by Gazef's death and stated that he thought of him almost as a father figure. 
===Shalltear Bloodfallen ===
Originally, Brain once used to look down on Shalltear and thought of her as nothing more than a foolish and arrogant demon that overestimated her abilities. After Shalltear rendered Brain's most powerful techniques completely useless with only her pinky finger alone, this caused Brain's spirit as a warrior to become broken, realizing that she is an entity who cannot be defeated by him because he was just a human. Brain would then go on and flee from her with everything he had. During his escape to the Re-Estize Kingdom, Brain was unable to sleep soundly due to having nightmares about her following him.
After meeting Sebas and Climb, Brain somehow managed to regain his lost confidence. Later on, Brain would come across Shalltear once again and already knew that he was no match against her. However, he was still determined to confront her again. Before facing her, he had asked if she remembered him and she claimed she didn't. Brain reasoned that it was because she would only recognize people strong enough to challenge her, which he stated that he expected as much. Due to his previous clash with her, he also believed he knew and understood Shalltear more than any woman he had ever known. Using his strongest abilities, Brain was able to at least manage to cut off a tip of the nail from Shalltear's pinky finger. This was tremendously joyful to Brain's pride as that meant that his entire life of training wasn't all for nothing. 
===Climb===
After seeing Climb survive being exposed to Sebas' killing intent, despite being much weaker than him and finding out the reason he could stand up to a being whose strength is on par with Shalltear was because he wants to protect the Princess, Brain went through a drastic change in his personality, restored his confidence, and began to care for Climb, helping him on many occasions. Compared to Gazef, Brain viewed Climb as a brother.
===Sebas Tian===
Brain greatly admired Sebas' strength and believed him to be as strong as Shalltear. Brain also believed that even if he and Gazef were to fight Sebas together, they would still be outmatched. He also saw Sebas as something of a guide or mentor as it was Sebas who explained to him that something made alone was fragile, but if he could make something with others and for others, then he would never be broken even if he suffered a defeat. Brain took Sebas' words to heart, which became the catalyst to Brain's improvement and regaining the strong will he lost when Shalltear defeated him.
=== Cocytus ===
Though the two met as enemies, because Cocytus came to meet him as a fellow warrior, he saw him not only as a formidable opponent, but also a top-tier character. Brain vaguely recalled having heard of Cocytus' name, from his conversation with Shalltear Bloodfallen, but did not dwell on it too much. The duel was brief and Cocytus defeated him with ease, but Brain gained the respect of the Ruler of the Frozen Glacier. Cocytus then ordered the Frost Virgins with him to preserve Brain's corpse.
==Trivia==
* In the Web Novel, he becomes a vampire under Shalltear Bloodfallen.Overlord First Half Chapter 30: True Ancestor Part 4
* Brain managed to chip off Shalltear's pinky fingernail by using "Nail Clipper", a technique that combined Fourfold Slash of Light and two other Martial Arts, the second time they met.
* Brain was the only person so far to know about the vampire's true identity known as Shalltear, but still believed that Honyopenyoko is another vampire that Momon had slain instead.
* His hair was blue because he dyed it.
* The author Maruyama intended to make him homosexual, but then decided against it and simply made him obsessed with sword skills.
* After the finals of the Royal Tournament, his fight with Gazef became legend and song and many powerful entities (Six Arms, workers, Windflower Scripture) started to take the names of Brain and Gazef in high regard.
*After their battle, Cocytus noted that Brain's attack rivaled a level 40. In the afterword, Maruyama claimed Brain had surpassed Gazef.
* Brain's body was frozen by the Frost Virgins by the order of Cocytus, but it's unknown what he wishes to do with it, though it is possible he has plans to have him revived as a personal servant to the Sorcerer Kingdom, considering how impressed with his stats and noted he can have the potential to become a strong warrior
==Quotes==
*(Facing Shalltear): "These foolish monsters that think they're the strongest, they're all the same. They think that humans are weak, that our bodies are fragile, our abilities nonexistent. But I will teach you how dangerous it is to underestimate us."
*(To Gazef): "Stronoff! We can never reach the world of the truly powerful, no matter how hard we try. As long as we’re born human, this is the truth. In the end, we're just children holding sticks. We're playing with swords now, but we are still mere children pretending to be swordsmen."
*(To Gazef): "Stronoff. Strength achieved from the sword really is garbage. It's useless in front of true power."
* (To Succulent): "The strength that you speak of is the same. We're probably speaking about similar things so let me give you a warning. Even if we claim that we’re strong, we’re nothing special."
*(To Gazef): "Well, I guess I won't be able to protect the Princess and it'll be a shame to not be able to train Climb any more... but Gazef, I owe you. I'll do any dirty deed you want with a smile on my face."
* (To both Gazef and Ainz): "Wait, wait a minute! Hang on, Gazef! I can always die alongside you! Don't go alone! My lord Sorcerer-King! Please, I beg you! I know this is shameless beyond belief, but this is a heartfelt request! Please allow us both to face you! I know it won't inconvenience you in the slightest!"
*(To himself after Gazef's death): "Why did you choose to die? Wouldn't it have been fine to run from that monster? Wouldn’t it have been like conserving your strength? Why?! If you had to die, I wanted to go with you!"
*(To himself about Gazef): "You... like this... I admired you... I wanted to die with you. Why wouldn't you let me fight by your side? Why didn't you tell me that I could die with you!"
*(To Vesture's female disciple about the Sorcerer King): "Not only have I met him, I bore witness to his duel with Gazef... hmmm, I still don’t know what happened to Gazef till this day."
* (To Vesture's two disciples): "I think the Sorcerer King is plotting something, but I'm not sure what exactly he is plotting, I don't have a basis for that thought after all. My instincts are blaring alarms right now, and I tend to trust my instincts without question."
*(To Vesture's two disciples whom praise him): "Stop flattering me. I'm not that nice of a guy. While it's true that I picked these children up from the slums, it was for a purpose. There were ones that were on the verge of death yet I still walked past them without lifting a finger to help. If you want to praise someone for their charity, do it to someone who actually deserves it — like the princess for example."
