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.

Uterlibet has the mind of two dragons, one extremely inquisitive, the other rather disinterested, and both extremely aggressive if provoked.  Uter, as the left head is called, is always curious to hear the opinions of others and is well-versed in literature, whereas Lib is content to sit back and let his neck-mate do all the talking.  And thinking.  And hunting.  All the work, really.  Many dragons believe that the right head is incapable of any controlling personality traits, but he's really just unfailingly lazy.

The exact meaning of his name is 'whichever of the two you wish'.
