On Cybertron, Energon miner Orion Pax sneaks into an archive and watches a recording about the creation of the first thirteen Primes, who were said to have perished in a war with the alien Quintessons many years ago, with the mystical artifact known as the Matrix of Leadership being lost in their battle. Orion is caught by security, though his friend, D-16, rescues him. Meanwhile, Sentinel Prime, the head of Cybertron, speaks about fighting the Quintessons and finding the Matrix of Leadership, the absence of which has caused Cybertron's Energon rivers to dry up, which the Cybertronians need to survive. After an explosion in the mines traps Jazz, Orion and D-16 attempt to save him, causing a cave-in that leads to fellow worker Elita-1's firing.
