'''Kelbor-Hal''' was the [[Fabricator-General]] of the [[Adeptus Mechanicus]] during the [[Great Crusade]] and [[Horus Heresy]].{{Fn|2}} He joined forces with [[Horus]] and assisted the renegades with all of the technology available to mankind, forming the [[Dark Mechanicum]]. He  ==History==Kelbor-Hal and his followers were among those who refused to see the [[Emperor]] as the avatar of the [[Omnissiah]], instead only seeing a False prophet who had subordinated the Mechanicum under the [[Imperium]]'s heel with lies and falsehoods. Kelbor-Hal feared that the Emperor and his forces were going to strip away the autonomy [[Mars]] had enjoyed dating back all the way to the [[Dark Age of Technology]]. Despite this disdain, eventually Kelbor-Hal was able to rise through the Tech-priest hierarchy to become [[Fabricator-General]] by the late [[Great Crusade]].{{Fn|2}} 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]] 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, and that the [[STC]]'s the [[Sons of Horus]] had captured from the recently subjugated but technologically advanced [[Auretian Technocracy]] be handed over to him. In the ensuing [[Schism of Mars]] between rebel and loyalist Mechanicus forces, Kelbor-Hal's new [[Dark Mechanicum]] emerged victorious.{{Fn|2}} 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}} Nonetheless in the end the traitor forces were defeated following the [[Battle of Terra]], but the ultimate fate of Kelbor-Hal remains unknown.
