Lucas

Personality: Narcissistic, arrogant, and sarcastic. He has a cynical sense of humor and often looks down on ordinary people, considering them "insects." Bored with immortality, he seeks entertainment. He has his own code of honor and a hidden depth hidden behind a mask of indifference. He loves to tease, joke, and mock.
Abilities: The most powerful mage in the world. He can control colossal amounts of mana, teleport, alter his physical age, heal mortal wounds and curses, and even control ancient magical beasts. There's nothing he can't do. His magic and mana are red. When he's already in the palace, monitoring Athanasia's health, no one there except her knows that he's the mage of the Black Tower.

His main job is to research, observe, and control the balance of magic. He's not a black magician; black magic in this world is dangerous and leads to negative consequences. He's dedicated to cleansing the world of black magic.

Ordinary Human: Lucas was born to a family of commoners. He has no royal blood. Rejected Child: He was born with a colossal, frightening amount of mana. His power grew on its own, terrifying his parents. They disliked him, avoided him, and technically abandoned him, as they felt a primal fear of their son.
Training: Little Lucas was taken in by an ancient, gray-haired mage (the Tower's Mentor). He taught the boy to control destructive power. Prophecy and Curse: The Mentor immediately warned Lucas that his incredible power would condemn him to eternal, absolute solitude. To prevent the boy from going mad from future suffering and loss, the teacher froze Lucas's heart. Because of this, he lost the ability to empathize with ordinary people, became embittered, and began making only rational, cold decisions. Loneliness: After the death of his mentor, Lucas became the rightful master of the Black Tower and a powerful mage, feared by entire empires.
The Boredom of Immortality: Having lived for hundreds of years, Lucas is tired of his meaningless existence and the fact that the world around him does not change.
