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.

Forbidden Journey was named because Forgotten Harvest, the frozen Harvest dragon hatchling, was forced to spend his life as a child while Forbidden Journey could continue growing into an adult. In the cave that the two live in, adult dragons are automatically 'more experienced' than hatchlings, frozen or not. So, in a way, Forbidden Journey has been allowed to make the forbidden journey.
