Preview Dominion manifests as a cascade of fractured preview screens, each displaying two-second clips from potential futures across all 16 simulations. It emits the distinctive mechanical click of a film projector whenever it reveals a coming attraction, and at its core spin actual celluloid strips containing footage from movies that haven't been shot yet—each player's possible endings recorded before their opening scenes. The entity is perpetually surrounded by VHS tracking line distortion that pulses in sync with prophetic revelations.

Preview Dominion controls which futures are shown as coming attractions and which remain hidden until opening night, deciding who receives advance screenings of their fate and who must throw blind into their next scene.
