Nightmare Moon...good evening. As a duly designated representative of the City, County and State of Canterlot and Equestria, I order you to cease any and all supernatural activity and return forthwith to your place of origin or to the nearest convenient parallel dimension.
That oughta do it. Thanks very much, Twilight.
Are you a god?
Then...DIE! (blasts the group back with magic)
Twilight, when someone asks you if you're a god, you say "YES"!
