pictureImperium Class Ultra Star Destroyer The embodiment of Palpatine's plans for extra-galactic conquest, the Imperium would have been as powerful as a Death Star, but much more mobile. Equipped with a small fleet of capital ships, thousands of fighters, and innumerable support craft, the Imperium would have had virtually unlimited range since it would also have carried several World Devastators to produce needed supplies. With this ship, the immortal Palpatine would have spread the Empire across the universe. Rumors suggest that the crew would also have been "immortal" as well, thanks to cloning equipment that would have been onboard. Thankfully, Palpatine was not as immortal as he had hoped, and the ship never progressed beyond initial planning before his final death. While some die-hard Imperials wanted to try and actually build it to use against the New Republic, saner heads prevailed and the Imperium remained only a terrible dream.
Is this fanfic or somewhere actually stated in EU because its the first time i read about it.
