===During The Great Treachery===
Perturabo is able to goad Dorn and his fists into a Trap on Olympia, which Perturabo has transformed into a massive fortification he calls the Iron Cage.The LL Iron Cage is less Grimdark than its Vanilla hammer version, its more like a standard seige (Though Perturabo now also employs warp magic into his fortifications, making it a trippy seige as well). Its significantly less devastating than on the Imperial Fists, however it does take a really long time to seige. Long enough for Dorn to be away at his post on Terra for Alpharius to sneak in, destroy half the Imperial Palace (and about half of the Custodes, and a good chunk of what was Asia and the Pacific) on Terra with an Archeotech Bomb, Kill Malcador the Sigilite, Mortally Wound the Emperor and Steal the Emperor's Right Hand and Heart as a Tribute to Tzeentch. Once he finally cracked Perturabo's Seige Perturabo was no where to be found. Perturabo then Blew up the planet of Olympia as an offering to The Prince of Pleasure for Demonhood.

The Imperial Fists, already exhausted from the endless months of intense seiging and warfare from multiple fronts, suddenly had less that a few hours to regroup, salvage their equipment, and make it to the transport ships (they were unable to teleport). Dorn and his legion barely escaped. And of the 30% of his legion he lost to the Seige of the Iron Cage, nearly two thirds came from those who were unable to escape, their souls now captives to the Prince of Pleasure as a gift from his favorite champion.
