The Altirocks are a string of rocks that hover over the sky of Wistad. Their existence is relatively unknown, with only a few weevs ever having been up there having discovered them. They were discovered by accident by Ard on one of their regular sky flies.
The map in the game "Sky Stones" is set on The Altirocks. It takes the form of stones floating in mid air, with each of the 5 levels taking on a different form and layout.
