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.

Kallen VI Stadtfeld, she was an egg that had been abandoned by her parents due to explorers touching her eggshell. Falling from her species' hill, she rolled down the valley and ended up in front of the abandoned digsite Blindcrow's Cave. It was a hot summer, and by great luck, or a touch of destiny, she cracked her egg. Having no parents, she would have died, but because she is such a naturally gentle Guardian dragon, she developped an alliance relationship with the other creatures who live in the valley. Now, fully grown, she is the proud leader of her herd, and takes on the role of foster parent to all the abandoned eggs who roll from the hills to Blindcrow's Cave.
