Editing Cromwald Walgrun (section)

===Post-Heresy===

After the defeat of the Warmaster, the Lions fled to avoid annihilation. Unlike many of the Traitor Legions, they did not make for the Eye of Terror. Instead they split into divisions and headed for the far rim of the galaxy, on the outskirts of Segmentum Ultima, raiding targets for supplies as opportunity arose to sustain themselves in their flight. They lurked on the edge of the galaxy and waited for the Scouring to slowly burn itself out, laying low and keeping their forces split to avoid being slaughtered all at once.

As the Scouring began to fade, the Lions reorganised their efforts, with the Legion once again falling under the iron fist of their Primarch. He led them to begin raiding and pillaging Imperial worlds across the edges of charted space. At first he did so with near impunity; his warbands landed and conquered in lightning fast strikes that shattered the defender's command structure and crippled their fighting will, then set about the task of rebuilding the world in Slaanesh's name. Those who did not convert were subjugated by those who did.

The momentum of these raids slowly picked up, until the Lions were no longer a force that could be denied or ignored. A task force consisting of several chapters of Space Marines, numerous Guard regiments, the Inquisition and the young Ministorum descended upon the slowly expanding empire of excess and begin reclaiming it in the Emperor's name. Heretics burned by the billion as the Crusade pressed on, hounding the Lions and bringing them to battle at every turn. The heretics' power was shattered when Cromwald, now a Daemon Prince of Slaanesh, was finally cornered and ultimately struck down. With their leader cast back into the warp, the Legion splintered and scattered. Several warbands were annihilated by the vengeful crusaders, but many escaped to scatter across the stars. From there they begin to pursue their own objectives and desires. Some fight their Primarch's war still in his absence, others fell to infighting, others simply wage war for the sake of the carnage and glory of Chaos. Only in the Black Crusades are the Lions brought back together in any meaningful fashion, where they relive a brief throwback to their glories as a Legion.
