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. Pyros are easily the heaviest of all Xenowyrm subspecies and they use their weight to their advantage. If scorching their foes with flames doesn’t finish them off, Pyros will use the weight of their bodies for sheer crushing power. They create their lairs solely in volcanic regions, where lava and billowing flames are the land’s most prominent features.

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.

Despite the capitalisation of RFATe's name, many suspect that she has some sort of control over fate. This is not true, and she insists that if she did have power over fate, that she would have used it to predestine herself to have the same physical gender she identifies as. In fact, she blames this mismatch on a Madder Jungle banana, Banana of fATRE, whom she insists is responsible for her "technical difficulties", as she puts it. She does have supernatural powers beyond that normally attributed to pyroxenos, but that power is over fat. She uses this power to get back at the fruity, green-and-yellow dragon she so despises by making him obscenely obese, after discovering that the life mana that seeps through the Madder Jungle makes attempting to burn or crush someone to death extremely ineffective. RFATe, meanwhile, is always beautifully lean, except when she wants the extra mass in order to crush something.
