As they neared the end of their Crusade in pursuit of Zymran, Captain Kruger's Ultramarines Company invaded Daizamm. Amongst the blood rivers that flowed on the world, the Ultramarines stormed a temple of Khorne that held a gate to a hidden dimensional realm, where the Chaos Lord hid. Before they could to reach the gate however, they had to defeat a large force of Word Bearers and Daemons led by the Bloodthirster Mailokh, who fought ferociously to stop them. The Ultramarines weathered the storm and defeated the servants of Chaos, banishing Mailokh back to the Warp and opening the gate to Zymran's realm. In the dimensional realm the Ultramarines located a fortress which held Zymran and the remnants of his forces. Captain Kruger personally led his Company in a long, hard-fought battle against the Chaos Lord, which ended with the Word Bearers' death and the end of the Ultramarines' Crusade.
