Grakhirt's Lair
A tribe of evil norkers led by a human illusionist threaten the town of Nolivari. The heroes must brave the wilderness, find Grakhirt's lair, and defeat him to ensure the safety of the local villagers.
A straightforward dungeon crawl against lots of norkers! When do you get to see those guys in an adventure? Lots of monsters from the AD&D Monster Manual II as well.
This adventure features a little bait-and-switch; the titular bad guy Grakhirt is assumed to be a norker, or gnoll, or some other monstrous humanoid, but is in fact a human illusionist/assassin!
Note: The adventure doesn't feature caves AND a dungeon, but since the caves are treated like a dungeon with doors and numbered rooms, this is listed as a dungeon adventure as well.
