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.

The Deep Sea Diver of Triag often swims around by the cliffs on the northwestern side of Triag. A small group of docks hang by the cliffs. A small little boat shop is on the shore, for the cliffs don't stretch very far in length, but only in height do they excel. The Deep Sea Diver of Triag brings back precious pearls and sea stones or other valuable things to the docks and the shop. The humans that work there feed the Deep Sea Diver with some of their catch as a reward.  She knows the humans will not hurt her, but the humans do not feel the same way. They still view her as a smart hunter that, one day, will kill them, but that thought has not even occurred to the Diver. She is fine with bringing precious items to the humans as long as she is given food.
