Arx Online

Arx: Latin for citadel, the fortified part of a city, usually the highest point and the last line of defense. Across the universe, all sentient beings have been targeted by the energy of chaos. The will of the universe creates a tower of insurmountable height to protect and train the survivors. Unfortunately, the black holes formed from the extinction of stars have torn through space, creating rifts in the defense of the tower. Chaos energy has begun to permeate these rifts and corrupt entities throughout the tower from top to bottom. Now 18, you embark on your journey to the top of the tower, hoping to discover a way to repair the tower defenses.
