Lighting is returned to the real world. After so long he expects to see the great nation of Equestria that he left. Unfortunately he is dropped in at the height of the thousand year war. The nation is split in 3 factions. The New Lunar Republic, the Solar Empire, and the neutral zones that are dotted across Equestria. He is in a neutral zone inside the Solar Empire, but he is the one pony who could stop one thousand years of blood shed. The only way is to get to Princess Nightmare Moon's castle and hope that the thousand year war will be changed if Luna is still some where inside the dark shell of Nightmare.
