Nexus Dragons are massive, volatile beasts surging with magical power. Each half of a Nexus Dragon’s body is infused with fire or ice mana, and it is believed that the unstable nature of these paired elements drives the dragon mad as it grows in size and strength. They are strict carnivores, preferring to feed on dragons and other creatures that naturally possess magic in order to bolster their own stores. As Nexus Dragons age, fire and ice mana crystals grow all over their bodies, enhancing both their power and viciousness.

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.

Surprisingly tame, so long as she is kept in a calm, non-volatile place and doesn't interact with anyone too excitable, Nuclear is not quite as dangerous as she seems upon a first glance. She seems to have her magic mostly under control. She tries to unleash it in swift bursts, attacking rocks and trees as a means of blowing off steam. It works well enough and keeps her stable enough to interact safely with other dragons. When calm, Nuclear is docile, quiet, and agreeable. She is not the social type, though, both for her own and other dragons' safety. She can occasionally get snappy when approached, though, usually, she just ignores others and goes about her own business. Though harmless when calm, it doesn't take a whole lot to get Nuclear excited and hostile. Dragons that are particularly uppity tend to encourage her to act out and get violent, not always by choice. Luckily, her rampages are always brief, though she could easily injure someone if they happen to be too close.
