Abyssal Horn Den Guide Expedition

Expedition

Abyssal Horn Den is an Expedition in AION 2 where you face Gargaum, Kapu, and Dhakan. Below: every difficulty and the bosses and monsters inside.

Formerly part of the Ferocious Horn Den before it was drawn into the Abyss, this den is now ruled by Gargaum, who has mastered the power of the primal Mau. Once defeated and exiled by Nuakum, Gargaum returned and subdued his former tribe through his newfound strength. When the full moon rises, he revels in the hunt, slaughtering even his fellow Mau.
