The home world of the Transformers - Cybertron - is dying. Energon, the lifeblood of the Transformers, is in scarce supply, sparking the one decision Optimus Prime has to make so that his race will survive. Optimus leads the Autobots in an attempt to man the last transport off his dying home, a ship known as The Ark.

Meanwhile, Megatron and his Decepticons have found a new world rich with energy and plan to suck it dry in a ship called The Nemesis. As both Autobots and Decepticons race towards the space portal to the new world, they must fight for their lives when the true end of the Cybertronians is near.

The once Golden Age of Cybertron is over... These are the end of days.

Or so it seemed....

When a Space Bridge accident sends Grimlock to Equestria, he must locate the other Dinobots or become enemies to the strange inhabitants that rule this new world.

But what happens.......when more than just Dinobots are sent to Equestria......

With Fall of Cybertron now released, this is the continued story of that horrid war, battles will be fought, heroes will fall, and the Autobots will never sacrifice freedom.....no matter what species they are fighting for.

Twilight Sparkle finds an ancient star chart which shows the location of another world, Earth, as well as a powerful teleportation spell capable of interstellar travel. Princess Celestia allows Twilight to go to the other world for exploration. However, due to the Changeling invasion during the royal wedding, the negative energies it produced also frees Discord from his stone prison, who also decides that Earth should be his new playground. Meanwhile the Autobots continue to defend Earth from Megatron, and his Decepticons; ignorant that a new player is about to release chaos upon the world. And Megatron is not about to let another would-be conqueror steal his prize. Equestria also has it's problems when Queen Chrysalis returns to Canterlot, bent on usurping Celestia and Luna.
Twilight Sparkle, and Optimus Prime must save two worlds from three powerful villains.

(This takes place at some point during the 20 year time frame between The Transformers G1 series Season 2 and Transformers: The Movie; and 1 week after the Royal Wedding in Canterlot.)
