Lake Arrius Caverns

Lake Arrius Caverns is a large cave north of Cheydinhal containing NPCs (quest-related). It contains four zones: Lake Arrius Caverns, Shrine Antechamber, Dagon Shrine, and Shrine Living Quarters.

Related Quests

• Dagon Shrine: Find and infiltrate the Mythic Dawn's shrine.

Notes

• If the quest has not yet begun, you can enter the cave and proceed as far as the door to the shrine, where you can kill the Doorkeeper and steal his Mythic Dawn robes, but the door itself is locked and the Doorkeeper does not have the key.
• Even after Light the Dragonfires is completed, you can still find Mythic Dawn enemies in this cave.
