Derpy and Twilight are called to Canterlot, much to the surprise of Twilight Sparkle, who wonders why the rest of the friendship group did not get an invite. They are directed to Warehouse M, and Pinkie Pie cannot help but jump with excitement. When they get to Warehouse M, they are greeted by Princess Luna. Luna explains about the Warehouse (see Warehouse 13, it is the same idea). They are shown around the warehouse, which is huge and full of artifacts. Luna explains that anything which is dangerous or not fully understood yet, ends up here in Warehouse M. She goes on to say that the place fell in disarray after Luna got sent to the moon, but now that she is back she wanted to restart it. Derpy is amazed by the place and Pinkie decides to see if there is anything that would turn the place into a constant party.
