Changes

The campaign was waged against [[Vatale Gerron Terentius]], a warlord of the [[Halo Stars]] who had sworn fealty to the [[Emperor of Mankind|the Emperor]] but had since gone rogue and betrayed his vows. Terentius began to attack world worlds that had already been brought into the infant [[Imperium]] and created his own rebel empire. Thus the Imperium responded with its full wrath, with the [[Emperor]] personally ordering that [[Luna WolvesHorus Lupercal]] , [[Primarch]] of the [[Horus LupercalLuna Wolves]] , deal with the traitor.{{Fn|1}}

When Horus struck at Terentius' s empire, he attacked with not only his own [[Space Marine Legion|Legion]] but also with elements of the [[Night Lords]], [[Iron Hands]], and [[Alpha Legion]]. The first blows fell far inside the borders of Terentius 's empire when ships inside the [[Hecuba System|Hecuba ]] and Hilicia [[Hilicia System]]s suffered reactor failures. The ensuing naval disaster consumed two battle fleets and stranded hundreds of thousands of reinforcements. On [[Yeno Prime]] Terentius' chief lieutenants disappeared along with their command staffs. On [[Jubal]], the spire [[Forge]]s collapsed as tectonic charges detonated in their foundations. On hundreds of planets disasters and cataclysms crippled Terentius' empire. These acts bore the mark of the Alpha Legion.{{Fn|1}}

Terentius , however , was a skilled commander and was able to reform and redistribute his forces. As he did this, ships from the edges of his empire reached the core of his realm but were filled with tens of thousands of corpses. The surviving crews brought word of entire worlds decimated by [[Night Lords|midnight-clad warriors]]. Terror spread throughout Terentius' s empire despite his best efforts to contain the news. To compound this disaster, Iron Hands began to move on his bastion worlds. As he moved to counter-attack, his strikeforce was intercepted and destroyed by the Luna Wolves. It is said that at this moment, when he realized that he could not win, that Horus came for him personally.{{Fn|1}}

A Sons of Horus Luna Wolves fleet arrived from the [[Warp]] and within minutes annihilated Terentius' s command fleet. Horus himself teleported aboard Terentius' flagship, accompanied by 50 [[Justaerin]] and slaughtered all they found. Terentius died unrepentant, laughing as he was impaled by the [[Talon of Horus]]. With their leader dead, Terentius' rebellion crumbled. However Horus, his pride slighted, acted uncharacteristically harsh and ordered the Night Lords, Iron Hands, and [[Ordo Reductor]] to decimate every one of the remaining rebel worlds. The fate of Terentius' s rebel empire would serve as an example to all who sought to defy the Emperor.{{Fn|1}}
