Changes

At the outbreak of the [[Horus Heresy]], there were high tensions between the various [[Magos|Magi]] governing Mars. Seeing an opportunity for a powerful new ally, [[Horus]] sent [[Regulus (Dark Mechanicum)|Regulus]] into this powderkeg and he was able to convince Kelbor-Hal to join forces with the Traitors on the condition that the autonomy of the Mechanicum be ensured, that the [[STC]]s the [[Sons of Horus]] had captured from the recently subjugated but technologically advanced [[Auretian Technocracy]] be handed over to him, and that the [[Vaults of Moravec|Martian Vaults of forbidden technology]] be opened for Mechanicum use. In the ensuing [[Schism of Mars]] between rebel and loyalist Mechanicus forces, Kelbor-Hal's new [[Dark Mechanicum]] emerged victorious.{{Fn|2}} However after the Schism Mars was blockaded by the [[Imperial Fists]] and Kelbor-Hal was contained on the Red Planet for the next several years, forcing to rely on his [[Nine Disciples]] to act as his emissaries in Horus' fleets.{{Fn|3}} Also during the Heresy, he oversaw the construction of the ''[[Furious Abyss]]'' in the shipyards around [[Jupiter]] for the [[Word Bearers]], after which it was used to attempt to destroy the [[Ultramarines]] [[Legion]] and their [[Adeptus Astartes Homeworld|homeworld]], [[Macragge]].{{Fn|1}} Following the [[Solar War]], the loyalist blockade of Mars was lifted and Kelbor-Hal was able to take direct command of the Dark Mechanicus war effort again. Arrogant and gaudy, he attempted to take credit for many of the achievements of [[Perturabo]] and [[Sota-Nul]] during the [[Siege of Terra]].{{Fn|4}}
