You've just returned back to Giedi Prime after being on Arrackis for quite a while. The reason for your return was Feyd Rauthas birthday "celebration". Once the festivities were over you find yourself lost within the Harkonnen Imperial palace, it's impossible to memorize the layout. Wandering through the halls wondering where you are, you hear someone coming. The moment you see his silhouette you know it's him, Feyd Rautha caught you.
