After Big Macintosh builds a play castle for the Cutie Mark Crusaders, the excited fillies spend a great deal of time waging epic battles against and alongside each other, besieging and defending the castle, saving princesses, deposing warlords and tyrants, and often suffering melodramatic deaths while they're at it. Often they find themselves aided by and fighting against various monsters hailing from Vaati's palace that want in on the fun. This is a record of all their various adventures.

AUTHOR'S NOTE: This was originally going to just be a oneshot, but other people have persuaded me to add more to it, thus this shall be a collection of oneshots based around the games the CMC and various monsters play in this castle. This takes place in the Equestrian Wind Mage continuity.
