The Ancient Guthix Temple is an ancient temple devoted to Guthix found in the While Guthix Sleeps quest. To access it, the player must have a Sapphire lantern. If the player goes to the Tears of Guthix cavern, one of the Light creatures can be attracted to the player, who can then ride the creature down the chasm and to the temple. After While Guthix Sleeps, players can return to the temple to fight Tormented demons.
During the quest, the player, pretending to be Surok Magis in order to get past Movario and Darve, goes into the temple and must open an ancient huge door within this temple guarding the legendary Stone of Jas by solving a puzzle concerning Herblore.
The Stone is protected by the Balance Elemental, a Guardian created by Guthix. It has remained there for centuries but during the quest is stolen by Lucien, a Mahjarrat who also possesses the Staff of Armadyl.
- When a player was at the entrance to the temple, the Air key, Water key, Earth key and Fire key could be seen floating in the blackness near the temple, easily visible on the minimap. These were removed in an update.
- When going down the chasm, during the cutscene there is a Cave goblin attempting to go down to navigate the chasm under Moravio's orders. This still occurs even after the quest is completed, and may be an oversight by Jagex.
