A new pony moves into town, and he seems very irritable at first, but when he accidentally rips a gap in spacetime that is quickly becoming larger and destroying reality, he takes the lead in a journey through the multiverse to stop the Dark One, an ancient evil entity that has escaped it's prison and is wreaking havoc across space and time.

So yeah.
NOTE: This story is, so far, a one-shot. I just make it up as I go along. However, when the story is finished, I will go back and smooth out the edges and remove any pointless things. So if you are reading now, check back after I've finished and revised the story; I think it will be a lot more enjoyable to read. Sorry, that's just my technique.:derpytongue2:
