Imperial Fleshcrownes are an active and playful breed. They are equally good at flying and climbing and while they are not good swimmers, they love to take an occasional dip. Fleshcrownes live in large social groups called “communities.” Adult Fleshcrownes share the responsibility of looking after the young, who are very playful and active. Even after maturing, they retain their curious and mischievous natures, often getting into trouble. The fleshy crowns on their head can be raised at will, and are usually erect when happy, excited, or scared. Fleshcrownes—being a very peaceful breed—are more prone to flight than fight. If threatened, they can raise their crowns while hissing in an attempt to scare off predators.

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.

Gaku has always been a bit theatrical, and since his hatchling days he's spent countless hours working on his dramatic posing and stylish walking. It's not uncommon to see him jumping from tree to tree, always landing with limbs splayed out and tail swept to the side, trying to find the most elegant way to show off his scales. Gaku's personal philosophy is that there is no part of life boring enough to necessitate a lack of fabulousness, and so even when talking about the weather, he exaggerates his gestures and tone of voice. He doesn't mind being considered silly, since for him that is much more preferable over being considered boring.
