Moonstone Dragons are named after the orb on their tails, which resembles the gem of the same name. They are nocturnal and gather energy through the absorption of moonlight with their orbs. They seem to glow with a lunar light and are a very gentle breed, feeding off of plants and the moons’ power.

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.

Doruga is the exact mirror of his absolute best friend Agurod. He and she enjoy finishing each others' sentences, flying around EG's Cave playing pranks, and confusing the other dragons about their true relationship. Despite popular belief, Doruga and Agurod are the farthest thing from mates; they are more like siblings. In fact, Doruga's true mate is Gift of Glory, the lovely silver dragon from Arakiahoga Forest. Doruga has been madly in love with Glory ever since she made her presence in the Cave official. Despite not feeling as if Doruga is her mate, Agurod feels some jealousy over the time not spent together when he spends it with Glory. She almost wishes they had never met even though she would never want Doruga to be unhappy.

Doruga is a playful and lighthearted dragon who enjoys playing pranks on dragons residing on Mount Hagsip. The Neelix Desert's and Hagsip's residents have always had a rivalry, and Doruga makes a point in continuing that legacy.
