Two-Finned Blunas are a very social breed of dragon, living in packs of dragons called “pods.” Blunas are very curious and playful creatures and several dragons in a pod will often “play” with one other, chasing each other around, tossing seaweed back and forth, and riding ocean swells. They are occasionally seen swimming alongside whales and dolphins.

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.

Coastline is an exceptionally friendly and compassionate ocean dragon. He strives to make everyone around him happy, even if it's at his own expense. He'll engage in fun games, tell corny jokes, or just do something completely ridiculous, all in an attempt to get somebody to smile. He works best in sizeable groups, particularly if they, too, are water dwellers. Coastline prefers being submerged. He has a difficult time flying and an even more difficult time moving around on land. On the contrary, he is an excellent swimmer. Maybe not the greatest that ever lived, like some of his siblings, but still impressive. Coastline is always up for a good game, especially if it involves a lot of swimming. He isn't the smartest dragon around, so he has difficulty understanding games involving puzzles or mazes (not that his claws are dexterous enough to handle such tasks, anyway.) Though not the brightest, Coastline is very loyal to his friends and will do anything to make them happy.
