Someone managed to travel through space and time and managed to gather a copy of the essences of villians throughout history. Created by forcing together the essences of unadultared chaos and an existance so fickle it has only appeared in the realm of fiction, early Discord and Daybreaker, this is how Furore was came to be.  
Furore is as fickle as the wind. He doesn’t care for the nature of his existance, only living in the present. He has access to a very powerfull pool of magic within himself, though he doesn’t understand the scope of his powers nor does he fully understand or control them. That said, there will always be an underlying insecurity, as he knows his very existance is unstable and is afraid to one day just fade out of existence.
