Aldennians still tell tales of the Spindlewood Hydra more than a century after its death. The eight-headed monster was a singular scourge, even compared to others of its kind. Spawned from some deep, black pit of the Night Hag, the Spindlewood Hydra terrorized the countryside around Mor Aldenn for a decade, slaughtering entire families, killing sheep, goats and cattle, and decimating caravans. A band of five brave adventurers finally managed to halt the creature’s depredations. Now, agents of the Night Hag, employing secret rituals and foul necromancy, attempts to return the hydra to life, only this time deadlier and more powerful. With the newly regenerated hydra the Night Hag hopes to weaken Mor Aldenn so that the City of Mages can no longer resist her armies.
