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.

Arcane Ripple is rather unusual as she comes up to the surface of the ocean more often than other Deep Sea dragons, just to check what's happening with her 'siblings'. When she comes to the shore most of the other dragons come out to meet her. She has quite powerful magic and will alert her family on land when she's surfacing by telepathy. She is very compassionate and vigilant.

Arcane's scales are black when viewed closely.

Her mate is Kezrit Ripple.
