Deep below the catacombs of Canterlot castle lies the crystal caverns where the most greediest of unicorns go in search of power and gems, but as legend goes that any who enter never come out. Just below the surface is a long and forgotten city of towering black structures which have lain dormant for many millennia, but recent disturbances caused by diruptive forces and a new found hate the forgotten city slowly awakens to counteract this new foe, this.......Love.

Hidden deep on the cold, unforgiving landscapes of the Crystal Mountains, two machines of immense power lay dormant for hundreds of years. A bulky, armored vehicle and a slender, heavy aircraft awoke with newfound sentience to the pastel colored country of Equestria, with no knowledge of what they were designed for. How will this oblivious machines adapt to the peaceful, colorful ponies that populate the majority of these wondrous new world? Only time might tell.
