Galvanic Wyverns possess a strength that seems impossibly vast for their size. They achieve this through their unique ability to extract magic in its purest form directly from mana. They then channel this energy throughout their bodies via the metallic conduits along their spines, wings, and tail tips, giving them their magically-augmented physical prowess, as well as the magical dexterity to lay devastating spells. However, once they have depleted a mana crystal, they are left vulnerable until they are able to harvest another.

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.

Purple is said to be very charming and persuasive, but he sometimes completely loses his temper without warning. He spies on his neighbors, and aside from finding it creepy, they're uneasy because they don't know if he does it out of curiosity, nefariousness, or what. The only dragon in the area who can prepare the roast bamboo smoothie he likes so much is also the one whom he watches the most, and Purple talks a lot about how impressed he is with this dragon's smoothie-mixing ability and how he would like to blast him with all his might, presumably his idea of repaying kindness. When Purple isn't in an obliterating mood, he melts people he doesn't like with his Caligene-Inspired Melt Spell. The spell is difficult to prepare and perform, and it's only worked once, on a hapless royal crimson who called him vagarious. He didn't know what "vagarious" meant, so he took it as an insult and drained the offender.
