The Raven Sign appears as a dark, ink-like mark on the bearer's skin that shifts like living smoke, depicting a raven in flight over a graveyard. The bird's eyes are tiny points of gold that flare when danger approaches, glowing brighter during high-contention moments and darkening to near-invisibility when elimination threatens. The mark grows perceptibly colder when rivals approach with lethal intent, serving as a supernatural warning system.

The Raven Sign serves as a shield against complete erasure - bearers cannot be entirely forgotten even if eliminated from the current culling. This creates the series' central promise: survival grants partial immortality within the Deadlands, connecting directly to the 'strong get remembered' doctrine that governs the frontier.
