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.

While Fuelius is one of the younger members of his herd, he almost immediately assumed a leader-like position (though not one that the other dragons necessarily respected) by seeming to take control of past living styles. He finds it his duty to ensure that the main den be properly arranged with only the best decorations, and can be rather OCD about how holiday parties are adorned, such as the placement of lights on the Christmas tree. Like his kind he rather enjoys intellectual conversations, but seeing as most dragons in his herd don't share the same obsessive interests, the 2-headed dragon is often out elsewhere pursuing knowledge his own ways. Both heads rather enjoy being given opportunities to assist others using their wits, and when there's no one else to talk to, the two would usually just chat endlessly away among themselves.
