Gold dragons are the ones most often killed by humans, who consider their scales to be extremely valuable. These golden scales grant them a high level of protection, similar to armor, and they use this to their advantage in battle.

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.

Guarra is the army's Second-in-Command and will be be the future army leader when Exaestuo steps down. With his armour-like scales, he is a valuable asset to the Herachus, nearly impervious to serious injuries at the forefront of a battle.

Guarra was always a fighter, even before he joined the clan. He lived a solitary life, stealing kills off other dragons. Shortly before he found the clan, he attempted to steal a Stone dragon's kill while she was on the scene. Both were evenly matched, but Guarra was eventually shoved over, nearly losing an eye to the rough rocks under him. Guarra picked himself up and fled, fearing of losing his life to the infuriated Stone. Years after the incident, he still has a large jagged scar under his left eye.

Guarra is mates with the clan's lead healer Opulentus, a relationship that proves useful out in the battlefield.
