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.

Isogram is not cute, but when she asks someone if they think she's cute, it is in their best interest to say yes. Sometimes, she is even kind enough to warn the individual that if they say no, she will "electro-cute" them. Those who say yes, laugh at her extremely clever pun, or otherwise react positively are spared and become members of her fan club. Isogram has the temper and powers expected of a typical Astrapi Xenowyrm and thus has a hard time making friends, but friends don't matter because she has a sizable fan club, full of people who admire her skills and think she is good-looking.
