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.

Sith lives in the same labyrinth of tunnels and caverns in the Scottish Highlands that is the home to nearly all members of the Mac Shoogle clan. The dragons have no complexly structured society, but there exists some form of hierarchy among them. Sith is second in command to all matters within their cave. With her firm stride she marches through her mountainous home, checking on everyone and keeping the peace between the innumerable different characters within the cave.

Unlike most Guardians, Sith possesses a weak form of healing magic. Her mother Nifty claims she was blessed by a faery, her father Shoogle claims it can be traced back to his White grandfather. Sith herself is inclined neither way, she merely finds it convenient when looking after an injured clansdragon.
