The altar is located at the main entrance of the Catacombs of Kourend. The altar can be used to teleport to the four sections of the Catacombs; doing so requires using an ancient shard, which is obtained from the monsters in the catacombs.
The locations players may teleport to using the altar include Demon's Run, Dragon's Den, Reeking Cove and The Shallows.
- Demon's Run will teleport the player to the Lesser demons in the north-eastern part of the catacombs.
- Dragon's Den will teleport the player to the Brutal blue dragons in the north-western part of the catacombs.
- Reeking Cove will teleport the player to the Deviant spectres in the south-western part of the catacombs. Note that Deviant spectres will deal a lot of damage if the player is not wearing a slayer helmet or nose peg.
- The Shallows will teleport the player to the Warped Jellies in the south-eastern part of the catacombs.
The altar can also be used to upgrade Darklight into Arclight by using three ancient shards.
