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.

"Rauhantuoja" means "the bringer of peace" in Finnish, and it tells everything necessary about this handsome guardian dragon. Rauhantuoja is a very relaxed creature who always knows what should be done and when. His presence usually calms down the other dragons, too. He tends to be a bit sleepy when it comes to watching over the eggs and hatchlings and he may not be belligerent enough to drive away all the hostile intruders; that's why he often spends his watches with some other guardian dragon. His best workmate is Waulish Viima.
