Changes

Terrible wars were known to have followed this chain of events but all ended with the Necrontyr's inability to vanquish their foes. Despite their advanced technology, they found themselves constantly outmaneuvered outmanoeuvred by the Old Ones due to their mastery of [[Webway ]] portals. Eventually, the [[Necrontyr ]] were pushed back vanquished to such an extent that they were considered little more than an irritation to the Old Ones and forced back to the outer dark of the halo stars where they were forgotten. This imprisonment lasted for centuries. As they sought to find a suitable weapon to unleash against upon their foes, the Necrontyr began to study their sun, whereupon they discovered ancient entities that resided on themthe star. These they made manifest and named [[C'tan]], or star-gods in their language, and used them as their new weapon against the Old Ones.{{Fn|1b}} Through the C'tan, the Necrontyr were transformed into a cold machine race of beings that became known as the [[Necron]]s. They were now free able to pursue their vengeance against their ancient foes. This time, the conflict was far different from the previous wars as the Old Ones' mastery of the [[Warp]] was now countered by the C'tan's supremacy of the material universe. In time, the C'tan began to dominate the galaxy Galaxy whilst the Old Ones' bastions were besieged and their nurtured races were fed upon like cattle by the eternal hunger of the star-gods. Entire worlds were razed, suns extinguished and entire star systems devoured whole by the terrible C'tan.{{Fn|1b}}

During the war, Necron legions are known to have breached the Webway and assaulted the Old Ones in every corner of the galaxyGalaxy.{{Fn|6a}} Despite their legendary patience and implacability, the Old Ones began to grow desperate and began breeding new forms of life with an even stronger connection to the Warp, with the intention that these manipulated species would have the power to channel their psychic might to defend themselves. Many warrior races were created in this manner; it is believed that the [[Eldar]], [[K'nib]] and [[Rashan]] ranked among their number. It took millennia before these new creations were ready and in that time, the C'tan along with their Necron armies extinguished even more life in the cosmos.{{Fn|1b}} According to Eldar legend, the paradise the Old Ones had created was now desecrated by the C'tan, whom the Eldar knew as the Yngir.{{Fn|1d}} Among their creations also were early [[Human|Mankind]], tree beasts that were part of their ecosystem but otherwise had no greater role defined for them by the Old Ones.{{Fn|1a}} This was the time that the Eldar referred to as the God War, fought between the C'tan-supported Necrons and the Old Ones aided by their successor races.{{Fn|1a}} During ancient times, the Eldar learnt a great many secrets of the Warp from the Old Ones.{{Fn|3}} From this encounter, the Eldar learnt technologies that led to the eventual creation of the Webway.{{Fn|2}}

By the time the Old Ones marshalled their forces, there were only four C'tan in existence, but much of life in the galaxy Galaxy had already been extinguished.{{Fn|1d}} Eventually, the hot-blooded Young Races were unleashed, sending the Necrons reeling as the power of the Warp was an anathema to them and they struggled to contain the advance of this new offensive. In response, the C'tan unified for the first time in millions of years and began the great warding, which was to seal the Empyrean from the material universe forever, thus countering the magicks of the Old Ones. However, a seemingly unforeseen side effect of the Old Ones began to manifest in this era as the Young Races' growing pains disturbed the Warp itself with this formless energy coalescing and older warp entities become became predatory as the Empyrean began to become transform into a more hostile environment. From cracks in reality, the denizens of the warp Warp sought entry into the material universe which forced the Old Ones to bring about the emergence of new species to defend their last strongholds. Among their creations included the green-skinned, hardy [[Krork]] and the technology-mimicking [[Jokaero]]. However, it was too late by this point with their intergalactic network being breached and with their greatest works and places of power being overrun by the horrors of the warp created Warp brought forth by their own creations. Among the most insidious of these entities were the [[Enslaver]]s, who dominated the minds of the Young Races in order to create portals for more of their kind. The [[Enslaver plague|Enslaver Plague]] became the final blow for the reign of the Old Ones; they scattered, their power forever broken.{{Fn|1c}}
