Plated Colossus Dragons are one of the largest dragon species. These huge brutes are notorious bullies—they prefer to steal food from other dragons rather than finding it for themselves. As their thick hides are impervious to most forms of physical attack, Plated Colossi simply ignore the other dragons’ protests, or lash the offending dragon with their club-like tail, which can easily break a limb. Plated Colossi have slow metabolisms and do not need to eat often, but they may consume nearly half their body weight in one feeding. These dragons are not incredibly clever and any discussion with them will often center around eating.

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.

Geocentrism has many conjectures—she even dares say they're theories. They were all unheard of before she thought of them, and she likes to share them as often as possible. These are ingenious ideas, for instance that disease is caused solely by bad air, and living things being born from puddles and meat, and most recently, the Sun goes 'round Valkemare. She renames herself to a term pertaining to her newest idea, which happens about once a season. Other dragons and humans can't convince her, no matter how hard they try, that everything she's proposed are already well-known. Geocentrism would snarl and say that everyone's copying her, and if she could make those squiggly lines that everyone likes so much, she'd put them in a book and write her name nice and big on the front.
