A slight cross-over between Doctor Who, XXXholic, and MLP
The Doctor and Twilight Sparkle return to Ponyville from one of their out-of-time adventures only to land in a suspicious stallion's yard. The stallion, who calls himself April Fool, believes their encounter is inevitable and implies that Equestria is on the brink of a great catastrophe, and that a price equal to their wish to save Equestria must first be paid.

Somber Rule, a unicorn born to the Crystal Empress, and older brother to Mi Amore Cadenza, over a thousand years ago did not begin his story as King Sombra, Tyrant of the Crystal Empire. In his quest for immortality to diminish his mother's burden of eternity, Somber Rule only had his mother's well being in mind as he delved deep into the secrets of magic, both light and dark. He only did what he thought needed to be done, and did not foresee the consequences of his actions.

I suppose as post note here, this is my first fanfic story, and certainly not the only one, but I wrote it a while ago, before Season 4 came out. I've been trying to work up the courage to post this. Technically, the Main 6 and Celestia do make an appearance in the story, they aren't the main focus of the story, and are only briefly mentioned; and I didn't really trust myself with writing characters to stay in character. Slight AU, since in the episode we see Sombra get blasted out of the city. And the last warning, this is really more of an outline for the story, so there isn't much spoken dialogue between characters, mainly a narrative sort of story.

Other than that, I hope you enjoy.
