Is there a story where the oc enters mlp, joins the mane 6 and change the course of history. Preferably quite long and include shipping between the oc and a pony. Thanks!

I got ideas but I can't write a story to save my life.

Does the OC need to be a pony?

It might take you a while to reach the OCs or the Shipping, but it's a long story, and they are fighting for the fate of the world
