The tale of two mechs on Cybertron before the Great War, one born in Iacon and the other thrown into the pits of Kaon as a sparkling. People like them were never supposed to meet, much less become best friends... so it makes sense that they were destined to become doomed lovers. Even before the great war, these two had plenty of dangerous problems to worry about as they worked to decipher Cybertron's past and gain support so they could speak to the council. Cybertron's elite will stop at nothing to stop the truth of their crimes from coming out and Cybertron's criminal underworld will stop at nothing to get the equality they have waited so long for. Street crimes, corruption, evil scientists, traitorous friends, age old secrets, divine interference-Orion and Megatronus face it all in their battle for love and peace. Chaos is sure to come. (Megatronus/Megatron & Orion/Optimus Prime)

this is kinda just a rewrite of the events of last and the first 3 epsoides of Transformers Prime. I've never writen anything about this fandom till resently, so sorry if it's bad. This is also really sweet, or well I tried. This is a bad dscription for the story, the story is way better don't worry.

When Optimus Prime turns against his own it affects the whole team but when it hurts the youngest the most the base starts to get glum but when Optimus returns it's not how the team would have thought!

The gladiator smiled, "Mm. You are so bright, so delightful, and so marvelous, and yet you are so far away from me, and too chaste to be possessed." "That's not true." Orion replied, cover his hand and snuggled into his touch. "I want to be yours." - Orion thought the gladiator was dating someone better than him, while Megatronus thought his archivist would never chose him. Both of them were too afraid to confess their love to the other. Maybe some jealousy moments and some alcohol may help?
