Geminae Dragons are known to be among the most powerful psychics of dragonkind. This power is used primarily to communicate with other creatures, but also as a defense mechanism. Though large, Geminae are not particularly well-suited for physical combat and thus rely on their psychic abilities to influence the thoughts, intentions, and emotions of anything that seeks to harm them. These dragons have no interest in fighting, either; they spend most of their time solving complex puzzles as a challenge for both heads to achieve together. Though both heads of the Geminae approach problems much differently, they are unparalleled in their desire to collaborate and compromise to reach a solution. When a Geminae puts its heads together, there is almost nothing it cannot do.

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.

Fleur and Gabrielle are very similar, both using their logic rather than their strength to escape situations. Although they are both very close, literally and figuratively, they have two very different personalities. Fleur, the right head, is the leader of the two, with stronger psychic abilities. Gabrielle, the left head, is often found daydreaming, not paying attention to where she is. They have to find a way to work together, and that often leads to long debates between the two.
