Seasonal Dragons take on the characteristics of the season during which they are born. Thus, eggs that are laid in spring match the pink flowers and green buds of spring, and those that are laid in the summer grow to depict the bright green of the forest trees and the yellow of the sun. Eggs laid in autumn display the bright colors of leaves falling from trees, and those that are laid during winter take on the appearance of the icy snow.

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.

Truly, Wheatley is the king of idiots. After GLaDOS' defeat, Wheatley was put in charge of keeping backup test subjects in their suspended sleep (while not as magically inclined as the Portals, Wheatley was at least able to maintain the spell), but after countless centuries, he even managed to screw that up. Every dragon in stasis died, save for one strangely silent female Magi.

After waking her up and offering to help her escape, Wheatley and the Magi made their way through the extensive network of caves below the Aperture Canyons, inadvertently stumbling upon GLaDOS after a time. After a small struggle, Wheatley gained dominance of the canyons, and with access to the immense wealth of magical knowledge GLaDOS kept to herself. He almost destroyed the Aperture canyons by forgetting to maintain the spell that kept the magma underground from erupting. However, thanks to GLaDOS and the Magi's intervention, this was averted.
