"When I first arrived here, I walked on the long bridge and looked down at the massive amounts of flowing sand rushing over the cliffs like a giant waterfall. It is perhaps one of the most spectacular sights I have ever seen."
— Tarduk, Glatorian Arena
During the Core War, Atero was made a neutral area, free of raids or attacks. After the Shattering it remained a symbol of hope for the Agori. However, the area eventually fell prey to Bone Hunter raids.
During the most recent tournament, the Skrall failed to appear, puzzling Metus, Berix, and Raanu, although Metus was faking his confusion. Leaving to investigate, they noticed a sandstorm brewing. It soon became apparent that it was actually an army of Skrall warriors advancing towards the arena, who quickly attacked, took control of and destroyed Atero.
Atero was situated on a strip of land in the middle of the Skrall River and made accessible by a bridge spanning the eastern side of the river. Vast quantities of sand rush by in the river, giving the semblance of a waterfall.
