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.

Yimalif's heads appear to be controlled by the opposite hemispheres of his brain. Namely, the right head, who prefers to be called "Yima", appears more left-brain-dominant, analytical and good at the sciences, while the left head, who prefers to be called "Malif", is more right-brain-dominant, spontaneous and gifted with the arts. They are much less amicable than other two-headed dragons, and have a lot of scars on their necks from fighting with each other.
