The camp is half of the third stage of questing on the isle, accessed upon completion of [90] Tear Down This Wall!. The other half is the Conqueror's Terrace, accessed via the Emperor's Gate to the southeast. To the north is the Lightning Vein Mine with further access to the Thunder Forges, and the Diremoor is to the southeast. The Bay of Echoes lies between the Beast Pens and Zeb'tula / Dawnseeker Promontory.
