Changes

'''The Howling''' was an event in 401.[[M34]]. [[Black Templar]] [[Space Marines]] ended the Catelexis Heresy by executing the [[Cacodominus]], an alien cyborg whose formidable psychic presence allowed it to control the populace of 1,300 planetary systems. However, the Cacodominus' death scream echoed and amplified 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 [[Sector|Sub-sectors]] slide into barbarism without the [[Adeptus Terra]] to guide them.¹
