"Call them what you will—Krell, Psyrens or Enslavers. Just one witch, unsanctioned, caused the destruction of Hive Skorpios when one of those things used her brain as a gateway to this world. Within three days the entire hive's population was reduced to drooling mindslaves. Within three weeks an entire continent was at war. And all because the governor thought his family should be exempt from the Psyker cull and refused to give his daughter to the Black Ships."
