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.

Life-mate to the cave's head-gatherer Svien, the couple were the original cultivators of the cave's maze-like garden, which has grown to provide a great deal of sustenance for their mistress's more herbivorous dragons while simultaneously providing their cave-mates with a lovely place of rest and recreation. Katla is known as a quiet dragoness, keeping mostly to herself and the plants she cares for during the warmer months and hibernating the winter away by her life-mate's side.
