This is Tiamat. He's a Dragon King, from Exalted. A Raptok, specifically. He used to be a high-ranking warrior in a cult that worshipped the cannibalistic, necrophagic god Han-Tha, but he somehow managed to get embroiled in a quest given to a bunch of Exalts by the Celestial Bureaucracy that involved somehow eliminating the twisted god without actually /killing/ it. For some reason, the Exalts decided that it would be a brilliant idea to forcibly bind the thing inside of Tiamat.
