Terrae Dragons are primarily herbivores who prefer to eat from the tops of trees. However, due to their massive size, they must rely on small, specialized scales to absorb and convert energy from the sun. Since they live in tightly-knit groups, this form of energy absorption helps preserve the forests in which these dragons reside.

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.

International Baccalaureate and his mate, Advanced Placement, are two of the hardest teachers in the cave. Their knowledge is vast, and they try to cram all that they know down the throats of hatchlings as soon as they hatch. The hatchlings that are brave enough to continue the torture IB and AP give them typically end up better prepared for adulthood. Or at least, that's what IB hopes for.
