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.

Glacier, like the other ice dragons in his owner's cave, was not raised by his parents, but rather by the ice dragon, Vexen. Vexen may be infamous for his hatchling murders, cruelty, lies, torment, assault, disturbing actions and more, but his owner still counts him as the most capable of the ice dragons of raising a hatchling. Glacier spent his time with Chaos and Peaceful Frost, trying as best he could to ignore and forget his guardian's frightening hobbies and learn to fight for himself and for just causes. Disturbed by Chaos's adoration of and one-sided amity with Vexen, Glacier left the two as soon as he could, alongside Peaceful Frost. Glacier has teamed up with Vexen's brother, Shadowfrost, in creating a plot to eventually rid the world of the callous ice dragon, and of Chaos if they so need to. Glacier likes his sense of justice and fighting for good meanings, but many in his cave are scared of him simply due to the dark stereotype that Vexen brought upon his breed.
