What do you do when you are the last survivor of a catastrophe that destroyed your home? With powers, you did not want, that approaching the domain of divinity? When you are then deeply alienated for things you cannot control or desired to begin with?
How do you respond to that, and what would the effects be? For some, the answer is obvious. Hide, pretend that they are the monster, that it is their own fault for it. But for others, both stronger and the weak, the answer is madness itself.
Though the question then becomes, what will occur when it acts its will upon the world, just as the world acts upon it? Find out just what a mind born into madness, seeks to make of the world around themselves.
