Elric of Melniboné is a 1972 fantasy novel by Michael Moorcock. It is the first original full-length novel to feature Elric, the last emperor of the stagnating island civilisation of Melniboné who wields the cursed, soul-drinking sword Stormbringer.

While some of his work hasn't aged well, I am still quite fond of several of Michael Moorcock's Elric novels and the first Corum trilogy.
