When Water Dragons mature, they lose the ability to survive on land, entering the water permanently. They are adept swimmers and eat whatever fish are in the lake they live in. They tend to inhabit the same lake for their entire lives, although a few live in the ocean and swim all over the world.

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.

Olorogos, is one of the many Aquatic-like Dragons, the pupils of his eyes where emerald green, when he gazed at a person he had a penetrating gaze, but commonly he was simply swimming inside his lake, eating and doing little. He didn't talk much (Assuming that in Dragon Cave dragons can speak, correct me if I'm wrong), his scales where blue while his fins where silvery white, he had a narrow visage and he usually did not like company.
