its been years since the war ended and peace was brought back to Cybertron with the Decepticons and the Autobots forming a truce and returning back to Cybertron and Optimus Prime taking his rightful place as the last Prime with Megatron now back to standing by his side just like they used to when they where just students with Optimus having once been Prima's student and Megatron once being Megatronus's student now back together as brothers once more and now Optimus is having to learn without his teachers guidance on how to do everything that Prima Prime, Optimus's old mentor and the Prime of Light and the Life blood of Cybertron, had to do on a daily bases and right now Optimus is making his way down to Cybertron's very core just like Prima did so Optimus can connect himself with Cybertron's core just like Prima was but now its Optimus's duty to do it and Megatron and some of the other old Autobots are following right behind Optimus Megatron: walks right next to Optimus looking around on high alert So this is what the inside of our planet looks like. (you represent as Optimus)
