Adramelech

Son of Chaos and brother to Khione. He and his sister are bitter rivals, and equally matched. A battle between the two can last for hours until one finally retreats or neither has the strength to continue.
The two siblings refuse to live peacefully while the other survives and have made it their life goal to destroy the other, believing that there is only room on earth for one child of chaos.

It is unsure what this creature's purpose is on earth.
Some believe it is patiently waiting for something. Perhaps it is waiting for the end of man, or the rise of an unholy ruler. Perhaps both.
Some have made it their ambition to train their whole life until they are fit to battle the beast [at least in their mindset]. To date, these attempts have failed.
Able to regenerate his body if badly injured by dunking himself in a pool of lava.
If locked in a battle he deems as worthy, the holes in his body will become so bright they can even cause blindness if stared directly into. He is able to spit burning hot lava at his foes and even the smoke billowing from his body is hot enough to cause charring.

Not much is known about this colossal creature, since almost all who meet him neve return to tell the tale. However, those who have managed to tread in his territory without detection describe him as a very lazy, egotistical creature who loves nothing more making someone’s life a living hell before he finally kills them. He is often found loafing about in his volcanic pools, or fighting those who come to challenge him.
He has absolutely no shame when it comes to insulting those who annoy him. He has, on more than one occasion, been heard taunting his victims mercilessly as they try to fight him- yelling sarcastic remarks, laughing in the face of an attack his foe thought would work, or even peering into someone’s personal life to bring up their regrets and mistakes, all of which taunt his victims into a blind rage which Adramelech seems to thoroughly enjoy.
He is not easily offended or enraged, and seems to always keep a cool head. The only exception to this laid back personality is when he is locked in battle with his sister, only then will he become enraged and take anything seriously.
