Codex Armageddon

"Never before has the Ork menace been greater. Ghazghkill has achieved what we thought impossible. He has united hundreds of warbands with but a single goal - the total and utter destruction of humanity in the Armageddon Sector. Arrayed against the barbaric horde is the greatest force of arms the Imperium has mustered since the time of Lord Solar Macharius. The fate of hundreds of worlds will be decided on the blood-soaked ash dunes of Armageddon, and we cannot afford to fail."
