Michael Scott Rohan and Allan J. Scott’s 1992 A Spell of Empire: The Horns of Tartarus is an alternate-history fantasy novel.
Apprentice alchemist and hobbyist musician Volker barely survives his master’s exploration of forbidden forces. Now without a master or home, the half-elf discovers that his magical talents and his musical skills aren’t good enough, or impressive enough, to secure employment … until Volker meets tone-deaf Ulrich Tragelicht of Worms, dealer in wines and spices. Volker is just the employee that Ulrich needs.
But first, some history.
