Princess Twilight sets up a war game for the Royal Canterlot and Crystal Empire guards. By kidnapping Luna and Cadance.
The guards thought she knew the rules. They thought she knew the guard manual backwards and forwards.
Sweetie Belle, Scootaloo, and Apple Bloom re-write the manual... and conquer Equestria.
