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.

A dragon of somewhat musical lineage, LastWillAndTemperament (often called Last or Tempera, for short) is actually one for comedy rather than music. She is often seen discussing her current plans and possible outcomes to skits with her mate BootToTheHead. Her favorite skits are those that Boot was the inspiration for and also have random boots flying at the actors involved. Because of this, it isn't uncommon to hear her randomly repeat lines from them at random circumstances.

Unlike her mother MountainOcarina, Last prefers to pull random pranks and get into various shenanigans in her downtime. This has gotten her into trouble with the Rokaku Handcuffs sub-clan and with various villages on more than one occasion. She mainly does the pranks for the fun of it and tries not to accidentally harm any dragon or human that becomes the target of the pranks. Otherwise, she'd be too busy working on skits to bother anybody nearby.
