The body of Sentinel Prime was about to be alive.

"Sentinel Prime" Ren said. "These things run on Energon, and he's out of it. He's in a . . . sort of a sleep mode"

"Let us begin" Optimus said as he took out the Matrix of Leadership

"That's the great Matrix of Leadership" Ren replied. "He holds the only thing in the universe that can repower a Transformer's spark"

"Sentinel Prime, we bid you return." Optimus thrusted the Matrix into Sentinel's chest, into his spark. The older Prime's body jerked as energy surged through his body before blue optics came to life though they held confusion and panic. Then, Sentinel had Optimus pinned on the ground, a blade coming close to Optimus' neck.

"Hold your fire!" Ren said

"Stop, Sentinel!" Optimus grunted. "It is I, Optimus Prime! It is all right, you are safe."

"There is nothing to fear." Ratchet added as he and the other Autobots came into view, some of them were looking at the Prime in awe.

"We are here." Optimus stated as Sentinel straightened up, head turning to regard the rest of Optimus' team. "You are home, Sentinel."

"The war... the war!" he said

"The war was lost." Optimus told him as he grabbed the Matrix that floated beside him before he pushed himself up. "Cybertron is now a barren wasteland. We have taken refuge here, on planet Earth. Its human race is our ally."

"My ship. We came under fire." Sentinel began, his voice heavy and thick from years of disuse. "The pillars. Where are the pillars?"

"You saved five of them, including the control pillar."

"Only five? We once had hundreds!"

"Excuse me." Professor Cerise spoke up from the platform beside the two mechs, making the old Prime turn towards her. "My I as, what is this technology you're looking for?"

"It is the ability to reshape the universe. Together the pillars form a space bridge. I designed, and I alone, can control it. It defies your laws of physics to transport matter through time and space."

"You're talking about a teleportation device, aren't you?" Professor Cerise asked

"Yes, for resources, for refugees"

"Refugees, or troops of soldiers, weapons, maybe bombs!" Professor Cerise said. "A means of an instant strike! That's its military function, isn't it?"

"It is our technology and it must be returned" Sentinel said

"Yes" Professor Cerise said. "If humans say so! You can't just bring weapons of mass destruction into our atmosphere! Kind of have to clear customs first.

"I will overlook your condescending tone if you heed the gravity of mine" Sentinel said. "The Decepticons must never know the Space Bridge is here. For in their hands, it would mean the end of your world"
