Major AU! The Winchesters had a simple plan...find the demon that murdered their mom and burned Sam's fiance alive. Twilight Sparkle had plans; Stop Nightmare Moon. In one universe...they would've- after much trial and tribulation(well more the Winchesters then Twilight if were being honest) -gotten their wish.

...this is NOT that universe, and both plans as well as both worlds...are about to go up in flames...
