In case Yorick really is the culprit behind all of this, as I suspect, I will need to get my secondary time machine operable as soon as possible to chase him down. While I'm doing that could you help me by going to these coordinates in your timeline:

N 40°46.805 W 96°43.964

Look for any historical signs of fire, explosions, or anything suspicious. If you find something I'll need to know the exact year that he escaped in order to try to thwart him.
