Coilfang Reservoir: The Slave Pens » Zones » WoW Armory Light

The Slave Pens are the first 5-man wing within the Coilfang Reservoir.  The instance mostly holds Naga and their allies. You can get reputation for the Cenarion Expedition until Friendly in Normal mode. Afterwards only the Heroic mode will grant you reputation (through out Exalted). To enter the instance in Heroic mode you require the Reservoir Key (Honored with Cenarion Expedition).

In Heroic Mode, the Slave Pens holds Skar'this the Heretic prisoner. He begins and ends the quest which allows players to enter the Serpentshrine Cavern. The quest involves killing Gruul the Dragonkiller and Nightbane in Karazhan.

Note: As of Patch 2.1.2, Serpentshrine Cavern no longer has a required attunement to enter. The attunement quest chain remains in-game, and can be completed if desired.

Starting with 2008, the Midsummer Fire Festival will feature a new boss in Slave Pens called Lord Ahune.
