"I don't expect you to trust me. You were brought here suddenly without much reason, and I'm sorry for that. So, allow me to give you both a proper explaination." Silver said as he tapped the Crystal. Upon doing so, it projected a hologram above it, displaying different branches, like a tree, representing the different timelines. "What you see here, is a projection of timelines. Each of these timelines are determined by everypony's actions and decisions. There are an infinite amount. But…" He stopped, looking to the projection as it zoomed into a timeline. This timeline looked much different, as it was a violet color rather than the other timelines, which are colored blue. Going into the, "corrupted timeline," it showed an event unfolding. In it, the Crystal Empire, being led by Sombra, were fighting against an evil Princess Celestia, and evil Mane 6. "As you can see, somepony has been changing history, creating these corrupted timelines. If these timelines go unchecked, it could cause the corruption to spread. This timeline, designated as the "Core Timeline," if the corruption reaches here, it could tear apart space AND time as we know it. I've been dealing with things like this, but this is far more then I can handle alone. That's why I called you two here. I need your help to correct these timelines, and find whoever is causing these changes." He explained to them with a stern expression.
