Sometime at the dawn of the Imperium but before the [[Horus Heresy]], the Eye of Terror was discovered by Imperial explorers in what was presumably a fairly remote region of the Galaxy, and Imperial scholars named is ''Cygnus X-1''. The Eye didn't come into prominence until it was later discovered by the [[Word Bearers]], who had arrived officially for conquest, but actually on a personal mission for renewed faith, and it was here that they discovered the [[Chaos|"Primordial Truth"]]. It would later be visited by the [[Emperor's Children]] and the [[Iron Warriors]], intent on an expedition within the Eye, in search of the Angel Exterminatus. Before embarking upon this journey, [[Perturabo]] had formally named it the Eye of Terror.{{Fn|7}}{{Fn|8b}}

For the [[Chaos Space Marine|Traitor Legions]], the Eye of Terror has been their exile, sanctuary, and safe haven for ten thousand years, from which they strike out at opportune, seemingly random moments. The Eye is also sanctuary for the most heretical renegades, fugitives of Imperial justice, and traitors throughout the Galaxy, and all are welcomed as fellow enemies of the Emperor and the Imperium.{{Fn|1}}
