Mount Boanga is an active volcano located on Safari Island of the Archipelago of Ierendi. Apes and Dire Apes are hunted around this mountain. The real menace of the mountain are the Griffons . Visitors come to hunt them or fight them in the air using flying potions. Rumors of an ancient lizardmen ruin located on the mountains near Mount Boanga are unconfirmed but locals of the village of both Calatupos and Pupami show ancient lizardmen artifacts on their homes who they claim come from those ruins.
