Magnesium Amphipteres are a rather violent species. They ruthlessly drive out anything that dares to trespass on their territory, and spend much of their time flying tirelessly in wide circles as they hunt and patrol their space. Often a single individual shows aggression between even its own two heads as they fight for food and control over their body. They are not social and will only come together to mate, after which the two dragons return to their own territory almost instantly. Magnesium Amphipteres are named for their flames: these dragons can breathe blindingly bright, powdery flame from both heads.

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.

Rage and Ruin fight over the pettiest things and only stop to sleep, eat, and drive away invaders in their territory. They try not to let outsiders see that they don't get along because a dragon whose heads work together is much scarier. There aren't many invaders because the land Rage and Ruin laid claim to is rocky and gravelly, and it gets searingly hot during the day. Ruin seems almost disappointed that he can't show off his fire-breathing more often, while Rage feels the same but would never admit it to the other head, whom he deems childish and inane.
