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 a different type of mana, making them powerful magic users. Thalassas are a unique variety of Xenowyrm in that they are the only subspecies known to dwell in marine environments. Their porous skin and slender build are perfectly suited for the aquatic terrain, but they can only survive for short periods of time on land. Powerful users of water magic, they can create large waves and alter currents with a simple thought.

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.

Like her older siblings, Namida inhabits a location particularly rich in mana. The lake that her living cavern is part of also connects to a river that spills into a small lagoon: within this small section of water are lilies and other flowers that grow upon the water's surface. The life mana that naturally resides in the lake feeds the flowers, causing them to "weep" small shards of crystallized mana when the blossoms open. Namida collects these "tears" of mana, saving them in a cache for when they are needed, as their powerful life affinity grants the crystals healing powers.
