The Wardens of Labes
"'I've tasted power like nothing before... Now nothing will ever be able to taste me... Quite Ironic, wouldn't you say?' - Watcher Kimble."The most notable beings of Dark Blood are The Watchers. The Watchers undergo arduous and rigorous training to take in the Mire. Most go through The Darkening, but some can go through just drinking The Mire to gain the effects.

The Black Riders
A rag tag group of bandits who live in the forsaken mountains. They drank what they thought was water and gained the abilities similar to the Watchers. They made their horses drink the Mire as well which gave them the ability to travel between the Mired Plane and the Physical plane.

Void Constructs
Literal constructs made of hardened Mire. While technically of the Construct Race, they still have Liquid Mire flowing through their bodies. These beings are usually never seen, and not much is known about them.
