Changes

The Interex maintained were a close alliance humans originating from [[Terra]] that created their own civilization.{{Fn|2a}} At a certain point they made contact with alien races such as [[Eldar]], who told them about the dangers of [[Chaos]] and the threat that the inhabitants of the [[warp]] bear to humanity.{{Fn|2c}}. Later Interex made contact with [[Kinebrach]] who were defeated as a result of a long war and subsequently entered their society, becoming its inextricable part. After that Interex encountered, defeated and localized the aggressive aliens [[Megarachnids]] on the planet of [[Murder]] ('''Urisarach''' in the language of Interex, meaning '''Spiderland''')who started to attack the frontier planets of Interex, infesting at the start of the conflict eight Interex's systems. {{Fn|2a}} During the [[Great Crusade]] Interex were encountered by the [[Luna Wolves]]{{Fn|2a}} and at that moment their civilization included 30 systems.{{Fn|2b}} The technology of the Interex was in many ways more advanced than that of the [[Imperium]]'s, but was not as strongly focused on the waging of war.{{Fn|2a}}

Devoted to fighting chaos, (they referred to it as 'Kaos') they regarded the [[63rd expedition]] skeptically, as they thought they might be tainted by it. They were in talks with Horus and his peers {{Fn|2c}} when a marine somebody{{Fn|2c}} (later it became known that it was First Chaplain [[ Erebus]] of the [[Word Bearers]]) {{Fn|2d}} tainted by the powers of Chaos {{Cite this}} infiltrated the '''Hall of Devices''', the Interex museum of artefacts and weapons, sabotaged the building to explode {{Fn|2c}} and stole a valuable and dangerous Kinebrach sword known as an [[Anathame]]. [[Battle of Xenobia Principis|Fights]] broke out between Space Marines and Interex forces until Warmaster Horus was successfully evacuated off planet. {{Fn|2d}} The stolen [[Anathame]], secretly taken by [[Erebus]], would be the weapon that would later mortally wound [[Horus]]. The Interex are confirmed to have been destroyed in an Imperial campaign before the beginning of the war on the [[Auretian Technocracy]].{{Fn|1}}

The Interex had incredibly advanced technology available to them. At first glance, many of Horus' warriors believed the Interex to be aliens in the shape of centaurs.{{Fn|2a}} Later it was found the centaur base was a form of mobile fighting platforms for Interex warriors. They would walk into the base, and form a centaur looking warrior with increased mobility.{{Fn|2b}} They also used a type of bow or crossbow that the warriors of Horus wrote off as decorative parade weapons,{{Fn|2a}} until a skirmish revealed that they could emit bolts of light fully capable of punching through [[Power Armour|Space Marine armor]].{{Fn|2x2c}}
