For the world of Aion, the Abyss is not just an endless space where you can fly and fight on wings. It is the main battlefield of conflict between the races. Here, the fate of fortresses is decided, and ancient artifacts that grant an advantage in battle are captured. Every fortress in the Abyss represents resources and power. Every artifact is a chance to turn the tide of the conflict.
The Abyss does not forgive mistakes. Legions of Elyos and Asmodians clash here, and the outcome of these battles affects the entire shattered world. Many can fly, but only the best survive and win here.
