@TobernSavage Michael Moorcock has a series of novels and short stories about his "Eternal Champions", one of which is Elric of Melnibone. Elric travels many worlds and gets involved with gods and demons. He carries a black sword called Stormbringer, which has a will of its own. It keeps him alive, but it is also very bloodthirsty and causes him much grief.
He is anemic. He is a sorcerer. He is not an elf, as I believe the Sidhe from the Corum stories by the same author were the elf equivalents. He needed drugs to function before getting that sword, which is a sword you may have seen in art before. He is also a dragon rider and a god slayer, and the Valerians in Game of Thrones are modeled after him.
