Jumping back on the chapter-fic horse with this - serious attempt at a ridiculous premise. XD I've been working on it for a while, so let's see how this goes.
With Cybertron recovering from its long and destructive war, Rodimus Prime journeys to the Seeker-controlled city of New Vos in order to reclaim a part of himself long forgotten. But a dark secret and a fight over New Vos's future threatens to destroy everything Rodimus has worked so hard to build, and will push his skills both old and new to the limit. Politics is a dance, and in New Vos, dance can be deadly.
It didn't take long for the newly-minted Rodimus Prime to develop the instincts common to most officers, aided by having so recently being only a lowest-rank soldier... (Link to AO3)
