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.

As a dragon that loves the coast, Aurum and her sister one day met a young, timid shallow water dragon named Matilda.  When Aurum and her sister aren't skimming along the water or playing they are with Matilda, whom will spend free time searching in the water for items of interest, which she will show to them.  Often times these items are shiny and Matilda will give them away to the sisters and in return Aurum and Argentum have found a way to allow Matilda to fly on their backs during a calm flight, as this is Matilda's favorite social activity and the breeze feels lovely to her.  Aurum has recently begun to talk to Volaire to see if there is a way she could give Matilda the ability to fly, feeling sad for the dragon at times.
