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.

Guardian of Heroes was stolen from his nest while he was still an egg. Taken by the god Zeus to be the guardian for Hercules, he has never known his family. Bound to a life of serving heroes, he laments the fact that he will never be able to have a mate or offspring. He does, however, have his eyes on a certain gold female. Despite all this, Guardian of Heroes performs his job with pride. He has been the guardian and protector of many of the world's most infamous heroes. One day he hopes that he will become like Hercules, and have his likeness forever more emblazoned among the stars.
