These fiends are the Thirst Slacker's favorite minions, serving as his commanders, honor guard and lovers. In turn, the quenchers universally loathe him. These horned demons are lovely in form, male or female, and dress in once-white silks spatted with the blood stains of countless victims. Why? Because quenchers exist to quench their bloodlust. They love to kill and they always hunger for more blood. Their relentless presence both spurs and damages their allies. Their weapons, polearms, are constructed from steel-hard cartilige and riddled with veins eager to suck blood from the wounds they open. This is why they loath the Thirst Slacker. His commands and needs taken them away from their simple blood hunger and they find his manipulations tiresome. Yet, they are bound to serve him.

Insidious Relief.
