When Twilight and Celestia experiment with a new portal spell, three trained gaurds are sent in to look around and explore. Only one comes back, but with a strange creature on his face. When the creature later dies, nopony thinks much of it, but when the guard later dies with a hole in his chest, things go from bad to worse… Please read and review! ( I know that's a little redundant but it was the only thing I could think of!)
