Deep Sea Dragons, as their name suggests, spend most of their time in the darkest depths of the sea. They have a bioluminescent dorsal spine that serves to attract prey and communicate with their own kind. As with many deep sea animals, they generally eat whatever they can manage to bait. They rarely leave the ocean floor, surfacing only during breeding season. When they do choose to travel to the shallower depths, they avoid bright lights and will only come up far away from shore.

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.

Ranenen is a good friend of Naroeva Amaurea. They are both calm and gentle. Ranenen does like to have a little fun now and then, however. Whenever the enchantress needs to go somewhere across the ocean, Ranenen pulls the enchantress's water chariot. When the enchantress found the egg Ranenen was in, it was on the shore beside some rocks. The enchantress gently picked up the egg and carried it to her cave, where Naroeva Amaurea watched over it until it grew up.
