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.

Guarnier is a fatherly dragon, though he's fairly young. Among his group of companions, he often is the one doting on the others, ensuring that they've eaten properly or have stayed hydrated. Though his frequent fretting often elicits groans of annoyance from his companions, it makes him happy to keep an eye on them. He is, by nature, a protector. He keeps an eye on his cavemates no matter what, even if it causes stress on his own body. Oftentimes he can be caught up late in the night, resting upon unhatched eggs to ensure that they survive.
