Fairy ice

Fairy ice was a weather phenomenon that was unique to the Great Glacier.

Description
Fairy ice was a form of precipitation comprised of minuscule granular ice spheres with the consistency of slush. On the ground it resembled regular snow, the only difference was that fairy ice shimmered like a rainbow in sunlight.

Fairy ice settled in depressions in the terrain. It was common for entire crevasses and valleys to be filled with fairy ice. Due to its granular density, fairy ice was similar to quicksand. An individual who stepped onto fairy ice began slowly sinking. They could be pulled out or pull themself out if they grab an overhang, otherwise they sank down until completely submerged and began suffocating.

Locations
The Shakkak Pit in Nakvaligach was filled completely with fairy ice. Fairy ice could be used as a defensive measure. An example of this was the innugaakalikurit village of Gomwemk, which had a trench surrounding the village that was filled with fairy ice. The tallest peaks of the Keryjek Ridge glimmered due to fairy ice deposits.
