When you go to see Twilight the next morning, her bed is empty save for a single piece of paper. "Meat me in the dining room." It says. "P.S bring the bag with Dash's marebits down, TIA #1A!" This is odd. For a start, since when did Twilight make such basic spelling errors? You are undeniably intrigued, however, and it's not like you're doing much right now, so with a shrug you pick up the bag next to her bed and make your way down the castle's echoing halls towards the dining room. There is another note pinned to the door, this one written in what looks suspiciously like crayon.  This one said "Knock before you come in Spike! : ) " It reminded you of Pinkie Pie. You knock on the door with your claws. The sound of muffled voices can be heard, as well as some magic, some metallic clattering and other strange sounds.
