On board the starship Lost Light, Rewind asks his crewmates to help him tell a tale of pre-war Cybertron in the hope that it will help Rung recover from his brain injuries. Two civilians find Senator Sherma's corpse hanging from a bride, a Decepticon symbol scrawled on his back. An autopsy leads Chromedome and Prowl to Translucentica Heights, where a second dead body-also marked with a Decepticon symbol-lands at their feet. Meanwhile, a police captain named Orion Pax learns of the death of the Matrix Bearer, Nominus Prime. Orion's contact within the Senate confirms that Nominus was killed by the head of the Senate's security forces, Sentinel, who is thought to be planning something involving the nascent Decepticon Movement.
