Mundus Cantormaris Dragons are a gentle, friendly breed of coastal-dwellers. Their annual migrations at the start of spring are among the first indications that winter has ended. They use their beautiful calls to lure people with a desire for peace to them in an attempt to make lasting friendships. It is considered a sign of good luck for one to hear their calls.

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.

Rightsize is a sort-of nomadic dragon, who occasionally stays somewhere like it's his home, but he usually leaves within a couple of months and never goes there again. He used to work for the Werkosh Do Center, where he performed magical tasks, but he was "let go". When he first heard the Fore-associate tell him he was "let go", it sounded exciting. Then he found out he didn't have a job any longer. The higher-ups said that while he was the friendliest employee there, they didn't appreciate how he would leave the Werkosh Do Center unannounced and be absent for periods lasting from a day up to several weeks, necessitating others to take his duties. No amount of singing or good vibes could convince the Fore-associate to not let him go, and another higher-up shut off his telepathy after he said, "Please let me keep my job" for the eighth time, so Rightsize eventually had to accept he didn't have a place at the center. After that, he decided not to seek more employment.
