In which I, Twilight Sparkle, (the biggest idiot in Equestria), fail miserably, utterly, and conclusively in my valiant endeavor to keep my decidedly-more-than-Friendship feelings hidden from one Rainbow Dash (the sexiest fastest mare in Equestria).

There comes a time when the light must go out; but how do you know if you've burned brightly enough?

Based off a story I was told a while back (read the author's note). It is Hearth's Warming Eve and a rich Stallion walks the market plaza of Manehatten looking for a gift for the most important pony in the world. Himself. Things go astray when a street mare makes off with his bits and does a little shopping of her own. Does this mare simply seek material goods? Or something more?

Twilight Sparkle wakes up on the streets of Manehatten with no idea how she got there. Things take a turn for the strange when a scroll appears in front of her, threatening erasure and signed by "The Reapers". Just what is this game that Twilight has gotten herself into, and can she survive for seven days?

After years of occult and magical studies, sifting through tomes of arcane lore and obscure history and myth, Twilight Sparkle arrives at a conclusion to her journey: an ancient, reconstructed ritual to try and penetrate the veil between her and the ultimate truths of the universe.
