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. Astrapi are easily the most temperamental of all Xenowyrm subspecies. Their unpredictable behavior—coupled with their masterful control of lightning magic—has the potential for devastating results. Most of their time is spent airborne, flying through the skies or circling mountainsides for prey.

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.

Underuse was a free-moving astrapi of Victory Hills before being imprisoned. The system of rocks, mana cups, twisted twine, and paper fans at the Googolford Center built by the folks in Advanced Spell-crafting B went awry for 14 seconds and teleported her from the sky right into the region's largest correctional facility for magical beings. The staff are confused whether she was transported to be an inmate or not, but out of caution, they refuse to set her free. Underuse is angry about being confined, though she's found a role as a cafeteria lady and enjoys that a lot. She likes experimenting with ingredients of all kinds, including pieces taken from the building and other inmates (although the boss put a stop to the former). She is paid as if she were a worker, but every night, she has to sleep in a cell. Once those dumb-dumbs at the Googolford Center figure out what went wrong with their Teleporting-Whatever-Doodad, she's going to give them a good zap for inconveniencing her.
