This labyrinth of caverns were dug by several ground-type pokemon which inhabit the desert of illusion. While it does not have the harsh sand-storms of the desert, it does have many lost trainers and travelers lurking around every corner. The pokemon within the cavern are aggressive toward those they believe are intruders in their home and may become hostile to these lost souls. Exercise caution when traveling through the sandy caverns, you wouldn't want the cavern to become your tomb....
