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.

Tales of vast beasts dwelling in the depths are common, but few creatures, legendary or non, come close to matching Malzimun in size. His lights are the only ones that shine in the deepest pit of the ocean, but he relies on no lure to bring prey to him; he is an active killer, and more than one water dragon has been dragged down into the abyss to fill his belly. But it is not only other creatures of the deep that must fear him, for his heritage is one of dragons not afraid of the shallows, and as such he surfaces far more often than do most of his breed; a single hole in the bottom of an unsuspecting ship, and he can sate his hunger on all the sailors he likes.
