At this point, the war has ended and the Autobots have won. Transformers from all over are coming back home to Cybertron. A lot of these Transformers are NAILS (Non Affiliated Indigenous Lifeforms, coined by Prowl), people who didn't choose a side and abandoned the planet when the war started. Optimus Prime renounced his leadership, reclaimed the name Orion Pax, and left Cybertron. There are two comics that are showing the aftermath.
More Than Meets The Eye: Rodimus, Ultra Magnus, Drift, and a crew of 200+ Transformers leave the planet in search of the Knights of Cybertron, the first Transformers who brought about the Golden Age of Cybertron and then left to spread peace throughout the cosmos.
Robots In Disguise: Bumblebee, Prowl, Wheeljack, Ironhide, and other Autobots do their best to bring order back to Cybertron. Starscream acts as the representative for the Decepticons.
Dark Cybertron is the current crossover between the two books and Shockwave is the main villain. Way back in the beginning of the war, he left Cybertron to seed other planets with Energon to see what properties it would gain.
