These caves are at the base of a lonely mountain between the packlands and herdlands. The entrance is hidden so that it only appears when the moon is in the sky. Once inside the entrance closes and questers are forced to go along a path lit by light blue crystals that glow until they reach a cavern. In the cavern there is a pool that doesn't ripple when touched because in the caves there's no real wind. This is where Austrila will appear.
