Equinox Dragons are a highly vocal, migratory breed, easy to find when they are traveling through an area and incredibly scarce otherwise. They are extremely skilled at following dates and times based off the movement of the sun and the moons, and follow their lengthy migration routes like clockwork. Large flocks of Equinoxes can darken the skies, and their calls, which sound like eerie flutes, can be heard from a great distance. Equinoxes are very social, and hatchlings are cared for communally by the entire group—it’s rare to see a solitary Equinox, and any stragglers who don’t have a flock will often attempt to join groups of other breeds of dragon.

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.

Small Brain and his brother Smooth Brains were raised by a copper and venturis who moved nests a lot, so he doesn't have any strong memories of places he lived in as a youngster. He knows he was abandoned when he was very small but doesn't know why, but he tries not to dwell on it because his adoptive parents raised him with love. Because his brother is purple and he is green, he's pretty sure they're not the same breed and not related by blood, but again, it made no difference to their parents where they came from. Small Brain helps gather resources during the day, but he sometimes can't remember what plants and seeds and stuff are on the good list and which aren't, so he brings back to the nest everything that looks interesting. His mum is happy to sort them out and always tells him he did a fine job while mussing his hair. He's really good at hide and seek, and though his brother can never find him, his dad can spot him from the sky using magic, and he wonders if that's cheating.
