Changes

Devoted to fighting chaos, (they referred to it as 'Kaos') they regarded the [[63rd expedition]] scepticallyskeptically, as they thought they might be tainted by it. They were in talks with Horus and his peers when a marine (First Chaplain[[ Erebus]] of the [[Word Bearers]]) tainted by the powers of Chaos infiltrated the Hall of Devices, the Interex museum of artefacts and weapons, sabotaged the building to explode 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.  The stolen [[Anathame]] , secretly taken by [[Erebus]], would be the weapon that would later mortally wound [[Horus]]. It should be noted that the Interex warriors were quite a match for the Space Marines under Horus' Command.  As [[Horus]] halted his attacks on the Interex, and the [[Horus Heresy|Heresy]] began shortly after. The Interex are confirmed to have been destroyed in an Imperial campaign before the beginning of the war on the [[Auretian Technocracy]].¹
