===Sheol IX===
However, the Lion knew that this advantage was fairly useless against the Night Lords as they existed as a scattered force throughout the Warzone. He needed them in one place to really take advantage of his new toy. So the Lion waited months before finally springing the trap, laying the groundwork by concentrating his Legion into a single massive fleet and leaving much of the warzone to the command of the mortal armies and local warlords. The Dark Angels would patiently wait until the Night Lords had regrouped into a single force.

To accomplish this the Lion [[Alpha Legion|"leaked"]] some information to his allies in the Mechanicum, causing them to practically abandon their position at Sheol IX in order to throw themselves, unsupported, against a renegade Titan Legion. This [[Perturabo|sacrifice of his allies]] created a gap in the Loyalist line that would be too enticing for the Night Lords to ignore. So when the Night Lords committed their full might to assault Sheol IX, the Dark Angels jumped among them and caught them with their pants down, with the majority of the Night Lords stuck on the surface and with their unprepared fleet trapped at anchor.

At least half of their ships turned and fled at the initial stage of the ambush, leaving their forces still disembarked on the planet below. The remaining half stayed to put up a fight, but of those, half again were captured by the Dark Angels.

Once again the two Primarchs fought, this time with the Lion putting Curze into a coma and leaving a power vacuum in the Legion.
