Manifests as a piece of desiccated leather branded with a series of tally marks that seem to multiply when examined under harsh sunlight, each mark representing a competitor culled by insufficient preparation. The leather weighs far more than its size suggests, as though compressed by the density of years without rain, and runs several degrees warmer than ambient temperature regardless of conditions. A faint scent of alkali dust clings to it permanently, the smell of earth that has forgotten moisture.

It serves as the arbiter that emerges when conditions turn merciless, stripping away favorable winds, forgiving terrain, and second chances to measure competitors solely by the reserves they built before scarcity arrived—determining who earned their preparation through discipline versus who trusted in circumstances that inevitably change.
