A Fallout: New Vegas/My Little Pony: Friendship is Magic crossover

The style alternates between omnipresent third-person and the Courier recounting his tale to... Well, take a guess.

"This is a tale said around many a camp fire here in the Mojave. Some will tell you its a tall tale made up by drunken caravaners to past the time on the long and winding roads, but this is a true story. So come take a seat by the fire I have a fresh piece of mole rat in the pot if you care to indulge me with an audience... the story is of the strange pair..."

(A/N: This story takes place before the events of Gear of War 3, and between seasons 2 and 3 of MLP: Friendship is Magic. I've never read most of the supplemental material for Gears, so forgive me if I get some of the background stuff wrong. I'll do my best to research it/correct myself.)
