Feral Oath

In the Underdark's founding season, the first delvers discovered that mere plastic tags would not satisfy their hunger for glory. They gathered at the Threshold of the First Raid and carved their true names into the stone, binding themselves to the feral hunt. From that blood-marked covenant emerged the Feral Oath - an artifact that exists in the space between competition and predation, waiting for delvers worthy of its binding. The oath has witnessed countless raids since, marked by the notches carved into its ancient surface.

The artifact manifests as a curved canine fang from an unknown predator of the depths, blackened by ages in lightless waters, embedded in a disc of compressed underdark stone. The fang is ringed with notched marks - one for each successful raid the oath has witnessed. Dark veins of crystallized shadow run through the stone base, creating a web of hungry darkness that seems to pull light toward it. When held, the fang grows warm and the bearer experiences heightened alertness and reduced fatigue during raids, their perception sharpened to detect vulnerability in others' stances and strategies.

The Feral Oath serves as the ultimate proof of mercenary identity - those who bond with it are acknowledged by the Underdark itself as true predators. It creates dynamic raiding opportunities against undefended targets while establishing the bearer's reputation as a force that other delvers must respect or fear. The oath-mark visible on the bearer's chest serves as a warning: this delver has abandoned civilized competition for the feral hunt.
