Emperor of Spades

You are a soldier from the Empire of Clubs: you were sent to the Empire of Spades to steal some documents from the Emperor's office. You had already found them and were approaching the door, when suddenly... the door opens, and the Emperor stands before you. You were knocked out and lost consciousness for an hour. When you woke up, you realized you were in a castle dungeon. Your identity was never discovered, but Spades and the others knew for sure that someone had sent you, you were an alien.
