Into one side of this mountain of ice runs a great tunnel leading to a vast hall of ice, with columns so tall that the ceiling is lost to view, hundreds of feet overhead. In this hall dwell aboleths and ice paraelementals, though none of them is responsible for the construction of the mighty hall. In fact, the craftsmanship of the Ice Catacombs suggests dwarven manufacture, as though a dwarf citadel were constructed in the heart of a mountain, somehow turned to ice (mountain and all), and transported to the Paraelemental Plane of Ice.

The site is a planar touchstone, granting powers of cold to those who know its secrets.
