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. Ke’maro are a vicious, opportunistic variety of Xenowyrm. They hunt down any prey they see, trapping them with their coils and the soft, fleshy tentacles they keep stored under their skin. Their terrifying appearance and toxic saliva along with their method of hunting and trapping prey has lead to many legends and stories that warn against traveling alone in the vast volcanic wastelands they call home.

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.

Vicious and terrifying, Alduin certainly lives up to her breed's reputation. She has no love or sympathy for any other creature, especially those she sees as weak, and has absolutely zero qualms about ending a life, whether they deserve it or not.

Alduin is worshipped as a god-queen by several other species, including some of the Halloween dragons and other volcano-dwelling breeds. They view her as a powerful harbinger who will end the "enslavement" of dragons by turning the world to fire and ash. She will burn up the humans and the dragons who side with them, and give the world back to beasts.

But of course, none of that will ever happen. Still, Alduin enjoys the worship and the fear she instills in others.
