Scorpionfolk have been awesome throughout most editions of the world’s oldest role-playing game. In “basic” D&D, manscorpions were tough, polearm-wielding opponents—subsequently revamped by Bruce Heard as the treacherous, translucent, sun-fearing Nimmurian manscorpions in Dragon Magazine 192. 3.0’s Monster Manual II included Sword & Sorcery’s scorpionfolk as a mark of respect. 3.5’s Eberron setting had scorpion versions of driders. And now Pathfinder weighs in—giving a nice nod to ancient Babylon with the girtablilu name—with these religious zealots.
All of which goes to show that girtablilus in your campaign can be anything you want them to be. For this entry, we’ll stick with the religious zealot angle, but for you the possibilities are wide open…
The Pale Claw girtablilus are so firm in their devotion to their jealous god that they cannot perceive the servants of other divinities—clerics, paladins, inquisitors, and other persons of strong faith are literally invisible to them. However, the Pale Claws are also expert spirit hunters who specialize in the Blind-Fight feat. So their visual impairment hampers them but little, and the ghost touch weapons they favor still work quite well against mortal foes.
The fiercely ecumenical girtablilus of the Saber Coast venerate all deities as holy. Hiring girtablilu guards has thus become a mark of wealth and prestige among the local temples…and many would-be temple thieves have taken to stocking up on antivenom as a precaution against summoned scorpions.
The Last Prayer girtablilus preserve the rituals and traditions of dying faiths, keeping the guttering flames of devotion alive. In order to weaken the demigod of strangulation enough to kill him, a party of adventurers must first slay every member of his Last Prayer sect.

In case you didn’t click above, Wikipedia says this: “Their heads touch the sky, their ‘terror is awesome’ and their ‘glance is death.’” That’s a ringing endorsement for a monster.
