You have an appointment with Abaddon the Despoiler, Admiral. It is 800 years overdue, and can't wait much longer.
Be careful, though. The Inquisition believes that the Planetkiller, as well as a Gloriana-class superbattleship "Vengeful Spirit", carrying the arch-traitor himself, are lurking out there. So, you better prepare your fleet well, before you engage them.
Glory to the Emperor!
