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.

Named after the main character of the Athenian tragedy, Eidopus is a dragon that has a strong bloodline and a great deal of pride, assimilating him into the role of a guardian dragon. His flaw however is that he is easily distracted, making him a bad choice for protecting eggs, but his friends Tahli and Kajii see no problem with this when they want to come visit him. They help him stay focused and often assist him in his duties, in return he shows unwavering loyalty to them. One of his favorite pastimes is solving riddles.
