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. Aquilo live high in the firmament and are almost never seen on the ground. They are all too happy to greet travelers going through the mountains, and also seeing their panic as the Aquilos dive from great heights towards them, only to change course at the last moment and soar back into the sky. Many Aquilo enjoy testing their agility and mastery of air magics in dangerous feats of flying at one another, only to twist and harmlessly pass one another in intricate patterns. They try, with little success, to get the more foul-tempered Astrapi to join in their games.

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.

Truong is one of the last remaining Pelagic Sorcerers of the Cumuliform Path, most of whom left or were ousted when the royal rule ended two hundred years ago. He and the other believers continue their studies and rituals a little more discreetly now. On most days, Truong does normal activities like playing games and participating in the flight club, so the people who know of the Sorcerers don't suspect he's a member. Every Sorcerer knows the tales of the Ghasts performing various feats before ascending through the Lens-Vent. Truong has dim memories from long ago that he believes are Ghastly in nature, so he's sure the Ghasts are real. He studies the whispers and texts in hopes of ascending, too. So far, he has managed to track down and sacrifice three nestmates he knew as a hatchling, in the name of the Path. Many people have negative feelings toward the Pelagic Sorcerers, even calling the group a cult, which is a mean word coming from those averting their eyes from the truth.
