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.

Jack Frost is a young Ice Dragon. With a personality as icy as his body temperature, it's no wonder that many of the other dragons in his clan aren't a very big fan of his. He is sarcastic, cold, blunt, and so brutally honest with the others to the point where he comes off as just being rude. The adults tell the hatchlings never to go near him, as hatchlings greatly annoy him. He is incredibly smart, and spends a lot of time alone in the library with Izar and Sapphiro, reading and even writing books. Stormy the Thunder and Asher the Magma are pretty much his only friends, and together the three of them form the Legendary Trio. He and Asher are pretty much exact opposites in a way, as Asher is quite childlike and innocent. The only time he leaves the cave is in the winter, as he is allergic to hot weather. He was found as an egg by Pyro the Magma, but he couldn't touch the egg without it melting, so he left it where he found it until Jack hatched before he brought him to the cave.
