Harvest Dragons are a large, flightless breed most often found in heavily forested mountains. Normally shy, these omnivorous dragons keep to themselves in remote regions, but in the fall they descend from their high territory to search for food—and lots of it. During the autumn months, harvest dragons will eat whatever they can find, from large and small animals to nuts and fruit. In the winter they retreat into large caves and hibernate until spring, living off the fat they have built up.

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.

Yazhu is famous among Damian's Crater Clan for his burrowing skills. Obsessive by nature, Yazhu spends every moment that isn't used storing up food for the Winter crafting caves, dens, and hollows in the earthy walls and cliffs along the coast near the crater. His workmanship is impeccable and precise, and he labors over every detail. On occasion, he can be encouraged into venturing into the tunnels that lead towards the opposing Island Clan in order to carve out shortcuts or alternate entryways into the valuable Mana Cave that the two clans war over. It is rare to find him sleeping for more than a couple of hours at a time during the non-Winter months.
