Azaezal was cursed long ago when he accepted a deal with his patron the dark one. He became a warlock and lost his face but gained power. With each soul he takes he grows in power and there are no greater souls than those of dragons. His dark magic is very useful in combating the draconic forces but it is suspected that it not just the souls of dragons he collects. His appearance is unsettling to most people so he almost exclusively works with Lilith.
