::Dear spark, Bumblebee got me thinking when we had a history night. What’s the accepted history of Unicron and Primus that you know of?::

It really shouldn’t fluster him so to hear Rung call him that. He thinks for a moment before typing his response.

::As far as I can remember, they were created together. Either that, or they just always were, but they were always together, and always at war. Light and Darkness, Order and Chaos, entirely opposite sides of ultimate power, too equal for one to destroy the other. Primus made the original Thirteen and their implements to fight Unicron, because by nature he cannot create something that isn’t himself. Together, they cast him out, but Primus had used most of his energy to make them and became dormant, becoming Cybertron.::

::This is what we were taught, but I’ve… seen more, in my brushes with both. Our elders didn’t seem to know that they call each other brothers, or that Primus never wanted them to fight. They want to be one but can’t, both drawn to and repelled by the other like magnets.::

Return to me, Megatron. You cannot escape my thrall forever!

He feels the pull again. The voice, the ache in his helm and his chest. It’s blessedly faint today, but it’s there. His frame and optics glow their unnatural purple and Megatron does his best to distract himself with anything that isn’t remotely related to Unicron. It only half-works.

A decision is made.

The lights in the sky had been caused by Cybertron itself. The planet was “waking up” with so much activity on its surface again, or so went the most common gossip. Cyertronians of all factions had gathered to watch the dancing lights, not quite hand-in-hand, but gathering without violence and dirty glares in large, mixed groups was a step in that direction. 

While his citizens looked to the skies, Megatron ventured underground, flying down into the Well of Allsparks. The core of their planet, home to Primus himself… much darker than it was meant to be. The warlord glared at the massive chamber filled with pure, unfiltered energon and nothing else. Just being here lit the dark energon in his systems prickling uncomfortably; he could only imagine how it would feel if the Allspark were actually present. 

Reaching up to lay his hand against the metal shell he’d once infected, Megatron growled. It was hard not to see all of this as some kind of cosmic punishment, despite the fact that their ambivalent god had told him otherwise. His optics glowed purple, reacting to his servo on the chamber. “…Without you, I have persevered. I clawed my way up from your depths and fought for everything that I have now. I’ve made mistakes. But now that I must fight for all of Cybertron… those mistakes have left me- all of us defenseless. I will not allow them to die for my mistakes!” 

His servo becomes a fist that pounds against the chamber wall, not even leaving a scratch. “I cannot not fail!” The offending fist goes numb with static and he staggers back from the wall, holding it to his chest. “I cannot… I cannot.” Megatron remains there, in the silence of the depths of Cybertron, until the hopeful lights overhead fade.

Only this last one listed has said anything coherent that merits a response. 

A: I resisted Unicron with every iota of my being. The only way he could get close to his goal was by overloading my mind and deadened sensory net to the point that I was rendered unconscious and even then he wasn’t fast enough.

B: It was the deepest, most intense pain I have ever experienced and I would gladly suffer it a thousand times if that is what fighting him takes.

C: …I assume you are referring to the counterpart that he has taken up residence within. In which case, that iteration of me had to be killed before Unicron could alter him so drastically. I will not fall so easily.
