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.

This Dragon was named for the twin prophets of ancient Troy. Both were prophets who were always right, but Cassandra was cursed to never be believed, and indeed, Cassandra laments that no one ever pays any attention to her. Cassandra is the more whimsical, dreamy of the two heads, and her more focused, analytical sister Helenus often belittles her for always having her head in the clouds. Cassandra likes to start projects, and Helenus usually has to complete them! However, despite their differences, the two get along surprisingly well for such different personalities inhabiting the same body. They can often be found devising new and interesting ways to hunt successfully, although Helenus's plans are usually the ones they end up using!
