Parasitic ice
Parasitic ice was a form of ice that expanded rapidly, covering and eventually crushing everything it touched. Its growth accelerated in the shade, or in the aftermath of a spider lightning strike. Zareh noted he had once seen parasitic ice enter a person's throat. ()

The surface of the Colony contained glaciers of parasitic ice. In 3189, the  crash landed on one of these glaciers and was nearly enveloped by the ice before it was pulled free by a tractor beam from Booker's ship. ()

Parasitic ice could be found on Kokytos. In 3190, Ensign Adira Tal became trapped in a patch of ice and had to be pulled free by their companions. ()
