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.

Tor and Fenris are the warlike defenders of the cave. Whenever there is a battle to be fought against a rival clan or some sort of intruder, they plunge into the fight, a fearsome sight with both heads biting and shrieking battle cries. Tor and Fenris are both respected and feared by their clanmates because of their vicious and skillful fighting, and most of the other dragons are very careful to avoid angering the two, although Tor and Fenris are usually quite calm and even-tempered.

  Along with being brutal warriors, Tor and Fenris use their two large brains to think up complex military strategies for their next battle. Sadly, the majority of their clanmates aren't intelligent enough to understand the plans, and most of the others think the two a bit crazy. Still, Tor and Fenris delight in inventing attack plans for imaginary skirmishes. Tor and Fenris are the mates of Solar and Lunar, another pair of outcasts.
