The '''Shadow Crusade''' was a campaign of the [[Horus Heresy]]. Making up the second theater of the [[Eastern Fringe]] campaign of the Heresy alongside the [[Battle of Calth|Calth Front]], it was a campaign by the [[Word Bearers]] and [[World Eaters]] against the 500 worlds of [[Ultramar]].{{Fn|1}}

During the [[Word Bearers]] offensive against the [[Ultramarines]] in the [[Battle of Calth]], [[Lorgar]] led another contingent of Word Bearers in conjunction with [[Angron]] and his [[World Eaters]] targeting the rest of [[Ultramar]]. The ultimate goal of Lorgar was to create a massive [[Warp]] storm known as the [[Ruinstorm]], which would create an impenetrable veil around Ultramar and the eastern half of the Galaxy, cutting off the largest of the [[Emperor]]'s [[Legions]] from [[Terra]]. The Ruinstorm had first been summoned by [[Erebus]] during the [[Battle of Calth]], but to mature it fully Lorgar needed to unleash a campaign of bloodshed and misery.{{Fn|1}}

Even after [[Terra]] became the focus of the war and the Primarchs left to wage battle elsewhere, fighting continued to rage in Ultramar from remnants of the Shadow Crusade. These included the [[Butcher Fleets]] of the [[World Eaters]] and the [[Argolian Massacres]] of the [[Word Bearers]].{{Fn|11}}
