Warhammer 40000 Dawn Of War Dark Crusade Expansion

Deep under the central desert of Kronus, a vast honeycomb of skull-lined tunnels and funereal chambers house the awakening mass of the Necron plague. Eons ago, these were the boulevards and squares of a great necropolis built to house the bones of the races who had fallen to the Necron purge, and ultimately for the Necron themselves to retire to. Over the millions of years, sand and rock had covered it all until ill-fated excavations awoke the deathless again.
