Seasonal Dragons take on the characteristics of the season during which they are born. Thus, eggs that are laid in spring match the pink flowers and green buds of spring, and those that are laid in the summer grow to depict the bright green of the forest trees and the yellow of the sun. Eggs laid in autumn display the bright colors of leaves falling from trees, and those that are laid during winter take on the appearance of the icy snow.

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.

Please Be Mindful wishes others would be mindful about his mind, which is rather mindful of the minds of others. What this actually means is rather confusing, but Please Be Mindful doesn't really mind when others cannot understand. After all, he believes that he himself is a mastermind with an excellent mind much better than others, though he never voices this thought: after all, he is supposed to be mindful of others' minds, and he is sure they would definitely mind if he told them his mindful mind was so much more 'full' than their minds could ever be.
