The low hanging mist of the cave brings a cool chill to your skin and after a while the dew begins to frost. Unlike the caves above this cave is far colder, despite the warm water that continually falls here. Though standing above the mist on the stairs the air is noticeably warmer.
When you all rejoin Tidus and Tersi they stand, Tidus far more tense then the odd robed Tersi, on what appears to be a perfectly flat stone floor covered in a thick slab of smooth ice. You cannot see further than a few feet in either direction and the sounds of the falling water make it difficult to hear. Aside from the spiraling stairs the area you stand in is rather featureless, with nothing of note in any direction that you can immediately see.
