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.

Being the son of an Ice obsessed with magic and a Bone Marrow whose old partner became an Undead, Hailveil has a keen interest in the supernatural. Along with his Arcana mate Infortunio, they especially like to study Papers, Cheeses, Zombies and Vampires. He is very curious and likes to interview the object of his attention almost to the point of irritation. If failing that (usually with the usually mindless Undeads or particularly violent Vampires), he observes them from afar. This backfires sometimes.

Some of the dragons he keeps an eye on don't mind him, like Endless the Paper and Full Moon the Vampire. Others, like Fade the sentient Undead and Maruku the Cheese, find Hailveil somewhat annoying but tolerate him.

Even among the feral Undeads, Windy and Kass don't pay him much heed, while the Twin Devils turn violent whenever he comes too close to either of them. Hailveil finds this particularly disappointing as he wants to figure out how they became zombies in the first place.
