===Mortarion===
Nurgle. Any ideas? Don’t have much.
<!---Considering that Papa N's specialty is endurance, maybe the Imperial Fists could become the Nurglite Legion, and the Death Guard become the Emprah's Reapers, silencing the worlds Sanguinius and Vulkan fail to placate.--->

Here's a yarn for you;
Mortarion's resentment of Father for having stolen his kill and trivializing his entire lifetime's worth of struggles up to that point festered and churned inside him for centuries during the course of the Great Crusade, which he and his Legion took a backseat for. When Lorgar started the heresy as a political revolt against Big E's deception of the populace and indeed His own sons, and overall hypocrisy all across the board, and just generally being a glimmering not-God jackass, Mortarion was on board right from the start, and allowed Lorgar's new sorcerers (led by that turd, Erebus) to infest his Death Guard with Chaos energies for the upcoming attempt at a Drop Site Massacre, and the Death Guard marines marched against the loyalist marines on the fields of Istvaan V in a gruesome display, spraying chemical weapons that corroded armour and set Astartes flesh ablaze with pustules and boils. The Death Guard marched even as their own bodies were torn apart, first by Bolter fusillades and soon, most disruptively for the loyalists to observe, by Nurgle mutations which split their rusting armour open like dead fruit skins and set their modified organs out in sagging lumps from gouges in their flesh. The fall of the Death Guard is marked as one of the most frightening and eye-opening parts of the Drop Site Massacre, as it revealed the new and dangerous threat of Chaos to the marines present. It wasn't just Daemons from a strange parallel dimension; it was the corruption of one's own body and mind.

Despite Mortarion's best efforts to coordinate the Siege Of Terra, the rapid splintering of their forces against the overwhelming defense saw the siege ultimately fail, though not before Lorgar fought the Emperor in single combat and reaped a mighty wound upon their Father. After Lorgar's descent into Chaos proper after they had retreated to the Eye Of Terror, Mortarion became Lorgar's right-hand man for all matters, sharing his preachy brother's seething hatred for the now "divine" God-Emperor. Mortarion is Lorgar's tactician and chief enforcer.
