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.

Kxinot Seto Thuwed is a bronze tinsel dragon. He is very noble and well-behaved, and he is also admired, since he is a thuwed and thus comes from a respected and ancient ancestry. Also, he is a bronze tinsel, and since his scales are the deepest shade of metallic brown, he is greatly revered by his clanmates and especially the females. Like all thuweds, his name is written in an ancient and mysterious language, but he prefers dragons to call him "Seto" or "Code", as his translated name is "The Code Dragon", which is fitting since if anyone happens to glance at his 5-letter code, they would realize it contains the letters of the master who started the noble thuwed lineages.
