The Grim Decree manifests as a heavy iron disk, dark as the vault's lightless depths, with ancient runes carved into its surface that glow with a dim, amber light - the color of dragonfire seen through stone. It is cold to the touch, carrying the chill of the tomb, and resists all attempts to damage or destroy it. The disk weighs heavily upon the bearer, a constant reminder of the decree they live under.

The Grim Decree serves as both judge and mark of survival within the Iron Hoard. Bearers have proven themselves capable of living under the vault's harsh law, their presence a declaration that they have survived the decree's judgment when others fell. It marks the transformation from challenger to veteran raider.
