Ice Dragons are fierce predators who hunt using their extremely cold breath. The breath of an ice dragon can freeze its prey solid in seconds. The body of an ice dragon is so cold that icicles will form along its skin no matter the outside temperature.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

Embedded in the mountainside of Aonach Mor lies a structure of brilliant glittering ice crystals. When the cave Uaimh's family lives in became too small to hold their numbers, Uaimh started using her freezing cold breath to fashion a building out of ice around the entrance, adding layer after layer to create a fortress of ice. If the menacing icicles around the entrance are not enough to keep visitors at bay, Uaimh herself will lash out at any passer-by.
