Serrati Wyverns are a fierce breed of dragon typically found in volcanic areas or in desert scrubland. With their keen vision, these fearsome predators can pick out well-camouflauged prey from the slightest movement. They are named for the double rows of serrated teeth that line their beaks, which allow these wyverns to maintain an unbreakable grip on prey while they tear into their target with deadly hooked claws. Though these dragons are combative with nearly everything, they are surprisingly well-mannered when raising their offspring in communal nests. Males, however, tend to be chased off as soon as eggs are laid.

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.

Slubber can hardly be considered bright, and he's very careless. He relies on his strength and sharp claws to get what he wants. "Slubber" is a nickname that he received when he was a youth, by a stranger whom he never saw again. To this day, he does not know what the term means and sometimes wonders if it's even a real word, but the lady assured him that it's a positive term. Slubber thought that it was very nice of her to call him that, because he had, not a minute ago, stolen her lunch. From then on, he figured that beating others into submission and taking their food is how he would earn respect and admiration.
