While Garth Nix has been working on his new novel, A Confusion of Princes, he has also been developing the background as a massively multiplayer online game (MMORG) called Imperial Galaxy using Facebook as its running platform. The novel is due out in 2009, but you can explore Nix’s universe now. Imperial Galaxy is open for beta testing to all willing Galactic Imperialists. All you need is a free Facebook account and the Imperial Galaxy application (free download here).
