The Ath cavern is a frightening place. For the most part of the year, the cavern is wet and uncomfortable. For a couple weeks the cavern dries up, even becomes a warm place to relax. In those moments, the strange creatures that dwell in this otherworldly place retreat further into the cave, to avoid any contact with sunlight. Occasionally one might encounter an eyeless mouse or a snake with legs. Other mysteries lurk in the depths of this place. Humans used to explore this place, looking for bacteria and new species.
