Mythraelus has spent the many years of his long existence in deep research of the varied realms of the Force, with a specialized focus on all Knowledge of the Dark Side. This immense knowledge has proven as much of a burden as it is a boon. Mythraelus has extended his life span beyond natural levels and has suffered mentally in his later years. He has developed a variety of quirks, tics, and a speaking pattern that appears cryptic and chaotic. But those who can overcome those quirks can make deals with Mythraelus and draw on his powerful knowledge. However, nothing in the galaxy is free and there is always a price to be paid. Mythraelus always exacts a cost for his knowledge; something of equal or greater value must be paid.

Mythraelus wasn’t born the dark and deranged Nagai that he is now. Years of isolation, traumatic visions, and Dark Side immersion have tainted his very soul. He is now more beast than man, a crocodile of a person. He cares not for the feelings of others, beyond what he can exploit and manipulate for his benefit. He respects only power and deals only in contracts and loopholes. He is a force of nature, blackness at its core, and truly has no empathy for innocence or the Light, except for when it benefits him.

Mythraelus is not known for being honorable. However, while his word may not be easily given it is never broken. When making contracts and bargains the solutions offered by Mythraelus are given in the form of a monkey's paw. That is to say, he will honor the letter of his deals if not the spirit of them. And he will do his utmost to ensure his solution is harmful to those who make deals with him, as long as it does not directly break the bargain. Those who can escape the bargain without breaking the agreement itself will be allowed to enjoy the benefits without further meddling.

There is nothing Mythraelus loathes more than an oathbreaker; those who break or dishonor his bargains will face his full fury. Mythraelus will focus on hunting them down at the cost of everything else, even if it causes him problems to do so.

Mythraelus speaks in riddles, and with varying levels of crazy. He is quite animated with his mannerisms and vocal with his hands. He loves a good story, and adding gimmicks or tokes to his dealings is a pastime of his impish nature. While he may come across as childlike, or even a little flamboyant, his voice is laced with his intellect. His words are full of double meanings and hidden agendas. He is not to be trusted, even as he soothes you of your worries.

Mythraelus is not the peak of physical domination. He instead chooses to wear down his opponent's mind, breaking their sanity and fracturing their psyche. He focuses on bringing them to their breaking point till they wish for the release of death. Only when he has exuded all the torture of their soul, will he then end their lives with his lightsaber or blade.

Of course, this means that his physical defenses are below standard. In a prolonged physical fight, he must choose to deceive his attackers with trickery and illusions or find himself at the gates of the netherworld himself.

Mythraelus is a villain. Those who know his true nature will not aid him in combat. For all his power he has nothing in the way of true allies or friends. He has no mercy for his “friends”, and even less for his enemies. Villains do not get happy endings. When pressured, Mythraelus will flee to save his own skin rather than complete an objective. This comes to conflict when outmatched by one he considers an oathbreaker; causing considerable mental anguish and potentially spelling his doom as he weighs the need to punish the oathbreaker against his need to survive.
