A free OSR adventure module for character levels 5-7
NEVER MEET FORGOTTEN HEROES! Long ago a half-elf, half deer-centaur named Jayne led a small guerilla band against the armies of an evil fae witch. They prevailed at terrible cost.
Over centuries, the Church erased all memory of Jayne’s fae nature. Monsters moved into her hideout-turned-sepulchre, still haunted by Jayne’s ennemies and companions, and a ghost longing to complete his vengeance...
In this 39-room dungeon, adventurers will discover the fates and true faces of Jayne and her forgotten companions. They may get rich, or become the latest victims of a centuries-old tragedy.
Designed for use with the Old-School Essential ruleset, compatible with most old-school pen-and-paper RPGs.
