This area is located at 1627W 564S, northwest of Qintarra in the Glimmering Forest. It is marked on your map by Raven in Qintarra when she gives you the quest to Remove the Humans from Falcon's Ache. Falcon's Ache is also the location of Ter'el's Altar which is a part of the Ancient Gods quest. The offering here is a Li'tani statuette.
