Gilded Bloodscale Dragons often spend hours investigating every minute detail of caves, making sure their living spaces are arranged exactly how they like. They crave intellectual stimulation and get bored easily. As such, these dragons prefer to lure in their prey using their sharp minds rather than brute strength, often engaging in battles of wits between their two heads to determine how best to proceed. Seen as eccentric by other dragons, they are often shunned by all but their own kind.

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.

Two-headed dragons are unique enough to deserve a separate classification from ordinary dragons. They have two necks, two brains, two mouths, but one stomach and one main body. The two heads usually work together, but there are times when they will fight each other, snapping back and forth. Their unique anatomy prevents them from breeding with single-headed dragons.

"There's something about the caves, something that bothers me. Something isn't right. And I'm going to find it." These were the last words of a brave dragon named Square Roots, who descended into the massive cave system underneath his clan many years ago. He hasn't been seen since, and some dragons wonder if he's still alive—maybe he did find someone (or some thing) in those caves no dragon should ever have seen, should ever have gone looking for. But secretly, the clan leaders know he is still in there, somewhere, for each month, a small scroll is found near a remote cave entrance, with markings mapping out underground areas he's explored. Though it seems a bit eccentric, the leaders merely assume that he wants to help his clan. But the truth is much more disturbing: Square Roots suspects that there is something sinister about the way the caves are formed, something hiding in what seems like an unnatural pattern, something he suspects is related to a thing he calls a "square root".
