Changes

Interex were tall humans with only one genetical genetic difference - a large bat-like ears that helped them use their unique language based on music and sounds. Interex still used language - an evolved human dialect of [[Terra]] - but very seldomrarely.{{Fn|2a}}

The Interex were a humans originating from [[Terra]] , that created their own civilization.{{Fn|2a}} At a certain some point they made contact with the [[Eldar]], who told them about the dangers of [[Chaos]] and the threat that the inhabitants of the [[warp]] bear pose to humanity.{{Fn|2c}}. Later , the Interex made contact with the [[Kinebrach]] , who were defeated as a result of a long war and subsequently entered their society, becoming its an inextricable part. After that , the Interex encountered, defeated and localized the aggressive aliens alien [[Megarachnids]] on the planet of [[Murder]] ('''Urisarach''' in the language of the Interex, meaning '''Spiderland''') who started . The Megarachnids had begun to attack the frontier planets of the Interex, infesting eight Interex systems at the start of the conflict eight Interex's systems.{{Fn|2a}} During the [[Great Crusade]] the Interex were encountered by the [[Luna Wolves]]{{Fn|2a}} and at that moment time 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 warwarfare.{{Fn|2a}}

Devoted to fighting chaosChaos, (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 somebody{{Fn|2c}} (later it became known that it was discovered to be 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|FightsFighting]] 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 wounded [[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 step 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|2c}}

The Interex also had automated drones throughout their society that were akin to Advanced AI , as opposed to the Imperium's more barbaric-like use of servitors (wiped brains serving as CPUs).{{Cite this}}
