At first glance, this cold cavern presents a strange and disconcerting vista—that of a desert valley under a starless, night sky. A stretch of sand covers the ground, a vista broken here and there by bits of strange, spiky shells or contorted, dead fronds that look like branches. A clear trail runs through the sand, undisturbed; apparently, numerous individuals passed through here, before.<br/><br/>A DC 14 Survival check identifies two separate groups, about three to six individuals each, passed through here.
