The Oxbow Testament appears as a curved piece of aged hardwood, darkened to the color of burnt umber, the outer curve worn smooth by generations of hands. Along its inner edge run deep tally marks - each notch represents a league completed, a river crossed, a mountain passed. The wood remains warm to the touch regardless of temperature, as if carrying the heat of constant labor, and emits a faint creaking sound when the bearer faces elimination, like a wagon wheel warning of structural stress.

This entity marks those who have proven they can maintain position in the wagon column through all four leagues without abandoning the collective. It serves as proof that the bearer was yoked to the journey and pulled their weight when others faltered, distinguishing the Homesteader from the Drifter through demonstrated commitment to continuation rather than surrender.
