Red has journeyed through time to change the outcome of a battle. Red senses another similar presence but finds nothing but a letter. Intrigued, she goes against her instincts and burns it before reading (As the letter instructed). So far, the rest is a mystery. Who is Red, how does time travel work? Who is the other person? Are they people? Where do they come from? These are all intriguing questions that might be answered.
