'''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 systemsas well as seventeen [[Dreadblade Knight]]s{{Fn|3}}. However, the Cacodominus's 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 were lost in the resulting upheaval and entire [[Sub-sector]]s slid into barbarism without the [[Adeptus Terra]] to guide them.{{Fn|1}}
