Dilvish, the Damned

Dilvish, the Damned is a collection of fantasy stories first published in 1982. Its contents were originally published as a series of separate short stories in various fantasy magazines. The protagonist, Dilvish, was sent to Hell by the dark sorcerer Jelerak when he interrupted one of Jelerak's rituals. The stories recount his adventures after he escapes Hell two hundred years later, with a handful of awesome, but impractical destructive spells and a sapient Steed named Black, and sets out for revenge on Jelerak.
