Yet they don't form communities in the same way that unadulterated Mind Flayers nest within the Underdark, and not only are they hunted as abominations by their own kin, they are also hunted across the planes by the Gith. The idea of how a large organisation of these undead cosmic slavers would come to be rattled around my head for a few weeks as I tried to work out how to fit them into my campaign narrative. Like all great big bads, they would need henchmen and other fodder to waylay foolhardy adventurers. Mind Flayers draw on cosmic horror, the sheer terror of the unknowable taunting adventuring parties with fresh, unimaginable trepidation at every turn. At any moment a player character might be about to star in a fantasy remake of Get Out, but yet when would Alhoons ever consider free willed servants? They were still Mind Flayers, driven with an innate desire to exert utter control over their agents becausealone are the superior people.
