Hivemind interactions with the Chaos Gods

• Valedor:

"The skein resounded to the triumphant laughter of She Who Thirsts. She was waiting for him now. Her presence pushed aside the limitless mind of the voidspawn."

• Devastation of Baal:

"Screaming warp fire crashed against the gestalt soul of the tyranids, catching it unawares. The delicate synaptic web that bound its numberless minds into one being shrivelled like thread in a fire. Never before had the hive mind been so grievously wounded. Its control over its trillions of bodies was violently disrupted. Hive fleet was cleaved from hive fleet, brood from brood so catastrophically that for a moment the hive mind ceased to be. It recovered quickly, diminished but alive, but that moment seemed to the hive mind an eternity of darkness. Trillions of its creatures permanently lost touch with the hive mind, and were reduced to unthinking animals. For the first time in its existence, the hive mind tasted death."
