The Glacor Cave is an icy underground cavern located near the Mahjarrat Ritual of Rejuvenation site. It can be accessed after completion of the Ritual of the Mahjarrat, either through an entrance to the south of the ritual site or via the fairy ring code DKQ. It was the cavern in which Lucien stored the Stone of Jas between the events of While Guthix Sleeps and the Ritual of the Mahjarrat.
Eleven level 112 glacors lurk within the cave's largest cavern, near the fairy ring, although they are unaggressive. A smaller cavern to the east of the main entrance houses the bane ore mine, which along with the Abomination Cave are the only locations in the game where bane ore may be mined. Movario wanders around the entrance cavern, studying the energy left over by the Stone of Jas.
After the quest, the residual energy left from the Stone of Jas will empower players who enter the cavern, enhancing their combat abilities in the cave as well as nearby locations such as Trollheim, the God Wars Dungeon, Fremennik Slayer Dungeon and the Wilderness for four hours of in game time. The empowerment remains with the player even upon death.
