Editing Age of the Dark Imperium (section)

==Vengeance campaigns==
The latest event to occur chronologically (even with how totally screwed up time in the Imperium), a newly healed Calgar (now back in charge of Ultramar following Guilliman leaving the system) leads the Ultramarines and a coalition composed of their Successor Chapters and Knight Houses across neighbouring corrupted systems that had been infested by Daemons during the Plague Wars. Amid one such campaign to free seven worlds in the Tartella System from Daemonic enslavement, Calgar notes the presence of an Ork Waaagh nearby and so simultaneously masterminds a hit and run campaign to break it before it could reach the Forge World Metalica. Using rapid strike attacks, the Space Marines win hundreds of battles against the Orks but their efforts only manage to slow the Orks down as their army is too vast and stopping them fully would mean the Ultramarines giving up the battle for the daemon-controlled worlds, which they are reluctant to do now that they’ve managed to free 3 of the 7 worlds. Fortunately the forces of Metalica were able to beat back the weakened Ork horde. Unfortunately they weren't able to enjoy their victory as the 3rd and 7th plague company of the [[Death Guard]] saw their weakened state, and supported by daemons, fallen knights, and a Titan legion decided to launch an invasion of the Forge World, beginning what was known as the War of Slime and Metal. Catastrophe was averted when the loyalist Knight House Raven and some forces from the Forge Moon of Deimos arrived later in the conflict and beat back the traitors, thus saving Metalica. Unfortunately for them, a later attack spearheaded by [[Typhus]] in the form of the Charadon Campaign was more narrowly averted, with Typhus delivering a Chaotic techno-virus to the Forge World and [[Be'lakor]] seizing House Raven's homeworld to corrupt the Knights there into his service as House Korvax.
