Okay, well, first of all there was these beings called the Primes. The Primes descendants from our god, Primus, and were the first civilisation on Cybertron. They maintained the Well of Allsparks and brought life to Cybertronians. They taught us how to take care of our planet, the Core and its energon.
The Primes helped defeat this creature called Unicron. It was this malevolent super-alien monstrosity that wanted to feed on the Allspark and doom the planet. Some say it was like the polar opposite to Primus Himself.
But the original Primes all died out. The title fell into obscurity. We mined away at our energon reserves, without thinking to reseed it. We were killing the planet, and ourselves along with it. Without their guidance, we ended up going to war once we hit peak energon, and class-warfare got too much.
But one of us became obsessed with placing himself in the lineage of the Primes. His name was Megatron. He used to be the greatest warrior of all of us, but he just went insane. Especially when he recovered some of the remains of Unicron, which he kept trying to commune with. He then corrupted the Well of Allsparks with the remains. Only the intervention of a modern Prime, named Optimus, was able to restore the Core. But, as if Primus Himself was punishing us, it hasn't reforged a single protoform since coming back online.
What if there’s no better word than just not saying anything?

...I guess.
