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.

Chips and Salsa are a glazier in Nworset. Unlike Atiar, who specialises in windows, they prefer to make lenses. Salsa has virtually unshakeable focus, so when she gets into a task such as smoothing a telescope mirror even sudden noises are unlikely to alert her. Chips, meanwhile, has an attention deficit and is constantly looking around. Chips pays enough attention to whatever Salsa is doing to help occasionally, such as switching out a tool in one of their hands to the one Salsa will need next while the latter head is using a tool in the other hand. Chips also talks to customers, and when about town she is the one to spot unexpected things such as misfits or stray drakes and avoid accidents. The two have a way of folding their wings where they curl the wing-fingers against their wing-arms and into their wingpits that makes them look uselessly small. Their wings really are the same size as those of any other geminae when unfolded.
