Idea!

Unknown to the Imperium, the Tyranids are actually being controlled by the free C'tan Tsara'noga, also known as The Outsider. In an act of revenge against those that betrayed him, Tsara'noga is leading the Tyranids to make landfall on planets with dormant Necron tombs concealed beneath the crust. In reality the Tyranids are being used as an engine to bring down the Necrons, but the lure of the Astronomicon causes the Tyranids to deviate from their assigned landings and land upon populated Imperial worlds.
