The Desert Sector is the main surface of Lyoko on the holomap. It's made out of a collection of dry, rocky plateaus. There is very little greenery, the only trees being scattered here and there. Here, X.A.N.A. can create sandstorms, break apart the plateaus, and even tilt them at 90° angles to immobilize the warriors. It is made up of two levels: the lower and higher levels.
