Ever once Optimus lost his memory and is stuck with the Decepticons, the Autobots back on Earth were struggling and panicking to get him back. That's until Ratchet decides to send you and Jack to Cybertron and to the Hall of Records to insert the Vector Sigma key in. He hoped the memories in Vector Sigma could get transferred into the key, then straight to Optimus when the time comes.

Right now, you and Jack entered the building in space suits (since you humans can't breathe on a robotic planet like Cybertron). But you guys were unaware that the old sage was present in the building...watching everything from behind the corner...staying hidden out of your sights...
