Equestria is under attack, more specifically, Canterlot. The Changelings have come back for vengeance, and it seems that they have succeeded. With the elements of harmony captured, both princesses in shackles, and Cadence and Shining Armor no where to be found, Twilight does the only thing she can do, call for help. But what happens if that help is a seven-foot, fully armored, S-3 Spartan? Only time will tell.....
(Cross-over with Halo: Reach. The mission six is pulled from is the Long Night Of Solace mission. The armor he wears is my Spartan.)
