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.

Akaru's territory is clearly marked by a line of scorched ground, and the area is as close to circular as he could manage to make it, for easier patrolling. He spends a few hours every day checking on his perimeter, constantly burning away any vegetation that dares to interfere with the boundary. Akaru is so proud of his method of marking his territory that he will willingly allow any prey to escape if it manages to cross the perimeter. This actually does not mean much, as Akaru knows the land well enough that any unfortunate prey that he's chosen to pursue rarely makes it even close to the edges of his territory.
