Over 100 miles “tall,” this vast mountain of ice floats on the Elemental Plane of Air, shrouded in cold fogs and howling wind. Local gravity gives the otherwise directionless location a sense of height and danger. At the apex, a blot of super-chilled yet unfrozen water lies trapped beneath a thin veneer of ice. It is easy enough to break through the coating to reach the water beneath, but the very air freezes soon after, once more encasing the liquid in ice.
Mount Sangaree (or more specifically, the unfrozen pool) is a planar touchstone. It grants powers of cold to those who brave its challenges.
