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.

Feraligatr rests in a cozy river delta, swimming peacefully with other dragons and living alongside the people who eek out a living on the river. Many have come to view Water dragons as a good omen due to Feraligatr's kind actions. Children tipping out of their canoes are often saved by a gentle flick of Feraligatr's tail. Feraligatr also helps fishermen by chasing the fish into their nets. In return, the Egeians along the Drile River celebrate annually by tipping over barrels of rum into the river. This rum is greatly enjoyed by the resident Water dragons and by other dragons who travel yearly to participate in the festivities.

Being a gentle dragon, Feraligatr would also participate in a game called "Throwing Balls". In this game of river dodgeball, the Egeians bring their best athletes to take turn throwing giant balls of seaweed at participating Water dragons. The Egeians have come to rely on Feraligatr participating every year, and to also win.
