Coastal Waverunners spend most of their time skimming the waves along the coast, snatching up their prey from the shallow waters. They have developed markings along the leading edges of their body that help disguise them as breaking waves. When they are not hunting, they enjoy playing among sand-dunes and shallow tide-pools. These dragons live in small but noisy rookeries. Some stories say Waverunners can fly for days on end without landing.

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.

Pterolach "CaveBorn" Baylant is a very loyal but shy dragon, offering her owner rides on her back. She also does this with some hatchlings she takes a liking to as well. Pterolach is very fast and is often seen competing with other dragons to see who is the fastest. Her sworn enemy is Pokihax Jakren, a whiptail. They are enemies because though Pterolach flies almost all day, Pokihax can easily out-speed her, but Pterolach thinks that Pokihax is cheating somehow. She is respected amongst her fellow dragons of her clan as one of the first dragons to be cared for by OmegaGrox. Her name comes from "Pterodactyl". She is part of the Baylant clan. She enjoys spending time with her childhood friend Garliad Jakren. She does not know who her parents are.
