Originating from a single species that thrived in ancient times, Xenowyrms have become an incredibly diverse breed whose appearances vary depending on their habitats. Each Xenowyrm subspecies is heavily reliant on the power of different types of mana, making them powerful magic users. Mageia, found exclusively in desert regions, are thought to be the wisest Xenowyrm subspecies. Due to their knowledge of the magi element, they are able to cast a variety of magics, including teleportation. Their beautiful yellow scutes are reflective and smooth like glass, making them very valuable to collectors.

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.

Xenotangle Weyr, known informally as the Tangle, is the creation of two enthusiastic mageias, one reluctant staterae, and one grumpy and long-suffering umbra. At the Tangle, xenowyrms of all types can find a community dedicated to preserving and passing on knowledge. Though rift dragons deliver most of the Tangle's packages, there are a few who don't trust notional rift dragons with delicate cargo. For those individuals, Usaebi will deliver their mail—though at a hefty cost, because he hates setting his research aside for other business.
