M34


 * The warp storm Gae-sann envelops the Kai system and absorbs it into the Eye of Terror.


 * Blackstar Crusade. Chaos forces emerge from the Eye of Terror to mount a crusade into the Ganglax Sector. Khorne champion Ekrak conquers M'laan XIII and turned it into a daemon world.


 * c 001.M34 The fourth Black Crusade. Destruction of the Citadel of Kromarch on El'Phanor before crushed.


 * The High Lords of Terra join the Ecclesiarchy and make it the official religion of the Imperium. From this point on, worshipping the Emperor of Mankind is mandatory.


 * 401.M34 The Howling: Black Templar Space marines end the Catelexis Hersey by executing the Cacodominus, an alien cyborg whose formidable psychic presence allowed it to control the populance of thirteen hundred planetary systems. Alas the Cacodominus' death scream echoes and amplifies through the Warp, burning out the minds of a billion astropaths and distorting the signal of the Astronomican. Millions upon millions of ships are lost in the resulting upheaval and entire sub-sectors slide into barbarism without the dictats of the Adeptus Terra to guide them.
