The tag manifests as a small iron disk etched with overlapping scar-like patterns that shift and rearrange when held to the light, forming crude images of previous vault incursions. It is warm to the touch and emits barely audible whispers that intensify when new survivors enter the arena. The tag glows faintly gold when in the presence of those who have earned their scars through genuine survival, distinguishing them from those who merely claim to have entered the vault.

The Scar Council serves as the Iron Hoard's accumulated institutional knowledge, providing strategic insight to bearers about the vault's dangers, hidden hazards, and the true cost of survival. It exists as a neutral power that transcends league boundaries, connecting all who have faced the dragon's trials regardless of which course or season they competed in.
