Guardian Dragons have large shields on the end of their tails. Although the shields appear to be heavy, they are light, yet nearly unbreakable. Guardian Dragons use their tail-shields, as well as their wings, to deflect attacks and protect others. Often, they will guard the eggs and hatchlings of a nest while others are away. They are generally peaceful, and will not retaliate unless necessary. They have no need to forage or hunt, as they are fed by those they protect.

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.

Moirreach mac Shoogle doesn't live in a cave, but in a rather shallow dug out hole in a small forest on the coast. Most of his family live deeper inland, up in the Highlands of Scotland, but Moirreach has a passion for the ocean and has made himself a den at the shores of the Moray Firth. He loves his wide view of the sky and water and can spend hours observing dolphins and whales breaking the surface of the sea before him. The Firth is full of fish and other creatures, making it an excellent feeding place for them. Even Moirreach will occasionally fish in these waters—he is no good at swimming and prefers soaring above the water rather than diving in it, but at the same time he cannot resist the occasional langoustine. He will avoid human fishers, not because he is afraid of them, but because he doesn't want to scare them, and hopes to retain the peace with his two-legged neighbours for many centuries to come.
