Transformers Prime Artifact

The Decepticon Megatron's sun did not disturb the radiance of the Earth's sky today, but the sensors of the Autobot base recorded a powerful surge of unknown energy in the Nevada desert.
The Autobots transformed and sped towards the coordinates at full speed. When the dust settled after the stop, Optimus Prime, Arcee, Bumblebee, Bulkhead and Ratchet found themselves on the edge of a huge, scorched crater. In the very center of it lay a massive metal box, covered with amazing patterns. On the top lid, an eight-pointed star was clearly engraved.
Ratchet approached first, activated his scanner, and swept a beam of light along the carving. His glasses flashed with surprise.
"Optimus, this is incredible..." Ratchet said quietly, checking the data against Clifford's archives. "These symbols... are the ancient Cybertronian language of the Thirteenth Prime."
“The thirteenth?” Arcee asked, her blaster ready. “The one whose name is lost to the ages?”
"Exactly," Optimus replied sternly, descending into the crater. "The box has been here for millennia. Let's open it, but be careful."
Using his power manipulator, Ratchet removed the ancient lock. The inside of the box glowed a soft blue. On a velvet bed of rare metal lay a device that looked like a folding armillary clock with many moving rings and the same mysterious ornaments.
"This is not just a chronometer," Ratchet whispered, continuing his analysis. "The energy source inside... it has the ability to warp space and time. This watch can completely stop time around its wearer and open bridge portals to the past and future."
"Such power in the hands of the Decepticons will destroy everything we protect," Optimus said, carefully taking the artifact in his palm.
“We need to get him back to base and jam the signal!” Bulkhead shouted, scanning the horizon. “If we sensed that surge, Starscream must have already sent a scout here.”
"I agree," Optimus Prime concluded, putting the watch back in its protective container. "Ratchet, open the space bridge. The Thirteenth's artifact must remain a secret."
The sound of the portal opening shattered the silence of the desert, and the Autobots disappeared in a green glow, carrying with them a relic capable of changing the fate of the entire Universe.

"We will always protect the earth"
