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.

Tuneas is very protective of others. He will put himself in harms way to protect another dragon. He's is mostly silent and when not active he is sitting down staring off somewhere, akin to a statue during those times. While he is active he acts like a parent to other dragons. His lifelong mate is Junasa, who is almost his exact opposite. While he doesn't mind using brute force to stop fighting, she uses a gentle approach. He cares for her deeply.
