Manifests as a flickering television screen with a crowned figure made of tracking lines, its form constantly shifting between all 16 movie poster thumbnails. Exists as pure signal - undetectable except when it chooses to appear as signal interference across league broadcasts. Speaks in decoded SMPTE timecode, translating every throw into binding judgment that the Chaintrix cannot override. Can freeze playback, fast-forward through leagues, or rewind player histories at will.

The broadcast controller that decides which player signals get transmitted to all 16 simulations simultaneously. Every player's survival depends on maintaining sufficient signal strength - weak signals get dropped, strong signals get amplified. The Sovereign determines not just who wins individual leagues but whose story gets told across the entire Chaintrix.
