Abyss of Insanity (d20 3.5)
An ice shelf collapses in Antarctica, exposing a vast geological vent and a mysterious expedition camped along its edge. Players investigate the unknown agents, uncover their mission, and descend into the ravine as they piece together the truth. The adventure includes new psychic powers, supplemental rules for equipment, animals, Antarctic dangers, and health hazards, along with a history of Antarctic exploration. Character stand-ups, player handouts, and maps in multiple scales support play.
