Befallen

Befallen is a sprawling underground crypt and tomb complex accessible from the Commonlands, designed as a mid-level dungeon for characters in the 15-25 range seeking experience and loot from undead creatures. The zone features winding catacombs filled with skeletons, zombies, and spectral undead, with the notorious "Befallen puzzle" door requiring key items to progress deeper into the dungeon. Players frequent Befallen for its reliable spawn of experience-yielding undead mobs and occasional valuable drops, making it a popular grinding destination for groups during the classic era.
