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.

Immotus is one of Primiserius' Second-in-Commands, and often regarded as the best out of the trio. When Primiserius is away with certain duties, Immotus takes over ruling duties until their leader returns. When she is not helping run the clan, she is working hard to summon Primiserius' heir to leadership. The process can only be performed at the peak of each cycle of the moon. Immotus has a suspicion that chances are lower during a new moon and are increased during a full moon, but even then the process is very difficult. With only one chance per fortnight, the trio practice their routine nightly to try and perform the perfect act which would lead to a successful summon.

Immotus is one of the oldest clan members and is often approached for wise advice. She has a habit of watching the sun set every night while murmuring an eerie chant. Rumours say that she is encouraging death to approach faster, but others deny it, saying that she knows she has a large responsibility to keep up.
