This thought seems familiar, somehow. Kind of Laundry RPG-ish, although a quick scan of the books didn’t bring anything up. Ach, well.
Operation FRIDAY CURIOSITY
Background: From 2013 to 2019 the human sacrifice death cult known mundanely as ‘Islamic State’/’Daesh’ (hereafter referred to as ‘IS’) operated as a proto-nation state in Syrian and Iraqi territory. IS attempted to mix its alarmingly brutal ritualistic practices with the maintenance and creation of a functional civic infrastructure, and achieved some success before the cult was eventually forced out of its physical territory. Preliminary checks by untainted Abrahamic theurgists have not uncovered conclusive proof of actual contractual diabolism, but ritual purification of important IS sites is ongoing.
