With the Imperium caught in millenia old grudges, a beast thought slain has returned and fleet Leviathan has reared its monstrous head once more. Nihlus will fall if the imperium does not act, and act decisively. There lies but one chance, a single stable pathway exists through the rift, the world of Ratis. Ratis offers a foothold in Nihlus from which the Imperium can launch a counter offensive and retake the fallen half of the Imperium. However, they are not the only ones who have set their eyes on this world.
An intense first week of fighting on Ratis has seen the forces of the Imperium gain the most ground, closely followed by the forces of Order, Choas and Reapers have gained a territory each but sustained casulties in the process.
