"I wasn't referring to either of you…" He said, mentally facehoofing. (facepalming for ponies, just in case if anyone gets confused) "Anyway. We will use this to travel to the corrupted timelines. We will start with something simple, a practice run, if you will. The timeline we're about to travel to has a small change." He said, tapping the Crystal. It projected a hologram, showing another event unfolding. It was during the wedding between Shining Armor and Cadence, Celestia and Chrysalis were fighting, their magic beams struggling for superiority. That's when a drastic change occurred. A dark aura formed around Chrysalis as her beam became much stronger, TOO strong. As soon as her beam made contact with Celestia, and explosion happened. Celestia fell to the ground with severe injuries. "T-Twilight…" Applejack started, her eyes tearing up. "She's dead…" The hologram faded. "Now you see the importance of this. What we need to do, is help fight against Chrysalis, but we cannot kill her. Once we weaken her, it's up to Cadence and Shining Armor to repel her and the Changelings." He explained sternly.
