Den of Haal'esh



The Den of Haal'esh is a deep chasm located in southwestern Hellfire Peninsula, beyond Dustquill Ravine. It is heavily populated by aggressive arakkoa and their kaliri.

By the time of the Cataclysm on Azeroth, it appears that the den was transformed into a Burning Legion citadel.

Speculation
The Den of Haal'esh may be remnants of an arakkoa force that once attacked the Tanaan Jungle and terrorized the Bleeding Hollow clan.
