Split Dragons use their sharp teeth and wings to hunt large animals and rarely eat plants. They are intelligent dragons who enjoy mental challenges, preferably alone; Split Dragons are normally solitary except during mating season. When mating, many dragons come together in a group to raise their eggs and hatchlings. These groups tend to be very noisy—reminiscent of a thunderstorm—and last only until the hatchlings are capable of surviving on their own.

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.

Sc8urge S1ST3RS, or really, just Scourge Sisters, is a Two-Headed dragon nobody really wants to mess with. They're known for being a vicious dragon who'll stop at nothing to torture other dragons and fight for her own needs.

One of the heads, who calls herself Vriska, has a weird penchant for 8's, spiders, and pirates. She'll often be the more reckless of the duo, and stop at nothing to do what she wants to do, without thinking of the consequences. Her cruelty far outshines the other Scourge Sisters'. It's not often that you'll see them without Vriska dragging them into a fight.

The other one, calling herself Terezi, enjoys the number 413 and cherry-red substances far too much for her own good. She's the one that really balances out the duo, thinking about their actions before taking it, but is just as vicious as Vriska when it comes to her goals.

And together, in one body, they are a practically unstoppable team. Challenge them and watch a dragon's head get taken off in the process.
