Changes

Interex were tall humans with only one genetically engineered difference - 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 rarely.{{Fn|2a}}

The Interex were humans originating from [[Terra]], that created their own civilization.{{Fn|2a}} At 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]] 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 an inextricable part. After that, the Interex encountered, defeated and localized the aggressive alien [[Megarachnids]] on the planet [[Murder]] ('''Urisarach''' in the language of the Interex, meaning '''Spiderland'''). The Megarachnids had begun to attack the frontier planets of the Interex, infesting eight Interex systems at the start of the conflict.{{Fn|2a}} During the [[Great Crusade]] the Interex were encountered by the [[Luna Wolves]]{{Fn|2a}} and at that time their civilization included 30 systems.{{Fn|2b}} The technology of the Interex was in many ways more advanced than that of the [[Imperium]], but not as strongly focused on warfare.{{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 somebody{{Fn|2c}} (later discovered to be First Chaplain [[Erebus]] of the [[Word Bearers]] {{Fn|2d}}) 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|Fighting]] 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 later mortally 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 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}}

Another example of Interex weaponry is the [[Interex mauler]]. A lightweight pistol-like beam weapon. The weapon has no kick and is absolutely accurate. It utilizes Kinebrach filament photonics. When fired it discharges collimated beam of powerful energy.{{Fn|3}}
