Inhabiting rivers and swampy regions, a Chelonian is a race of reptilian humanoids bearing resemblance to long-necked snapping turtles. Is it normally content to remain within its own small societies, but on occasion a more adventurous individual can be found. A chelonian is protected by thick scaly skin, as well as a shell-like growth that covers their backside except for its thick tail. A chelonian stands about 5 feet tall. However, its neck can stretch out to make it up to 8 feet tall for very short periods.

Chelonians have their own language, and adventuring chelonians always know Common as well. Chelonians are natural enemies to lizard men, often competing fiercely for the same resources.
