The Inquisitors had no families. In Sammoril, only commoners became Inquisitors.
This signified that they belonged to no noble's sphere of influence, only to the Goddess.
Or rather, they believed they belonged only to Lolth.
Because of their lowly origins, commoner women who lacked the wealth to offer sacrifices to Lolth yet still became High Priestesses often needed far more fanatical faith and devotion to win the deity's favor.
After all, they had no family treasury backing them, nor generations' worth of accumulated offerings to squander. They could only carry out Lolth's oracles with frenzied zeal and follow her doctrine, proving their worth through action.
And once the Goddess's favor truly descended, as snake heads swelled and sprouted from their Serpent-Head Whips, these already fanatical female believers became even more convinced that their faith was righteous.
These mutually reinforcing beliefs completed a closed loop in the commoner Priestesses' reasoning. Their piety earned them divine favor; receiving divine favor, in turn, made them even more devout.
This cycle drove them to ever greater extremes, making them increasingly eager to offer more sacrifices to the Goddess.
Yet as commoner Priestesses, they lacked the wealth to honor their deity. To keep answering this supreme "favor," the Inquisitors' thinking grew increasingly extreme, until they finally abandoned all material desires and devoted their bodies and souls entirely to their deity.

Protect the Holy City. Purge the "filth."
The Inquisitors had no self-serving motives whatsoever. They coveted neither wealth nor flesh, and their lives were downright austere. They did not even particularly pursue power-at least not power
