i agree with the superstition kinda thing, but even in an npc tool it would work pretty nicely as a plot moving device, i guess what i have imagined in my head is a slight deviation from your current setting concept, which in essence throws that veiled fantasy under the mortal world, sortof akin to the sci-fi channel adaptation of "the dresden files" yeah there is magic, and mystical critters just outside the realm of standard human perception, but to manifest anything really worthwhile you practically kill yourself, perhaps something like what i'm talking about would go great as an acessory supplement, i mean there is a real world basis to a lot of the occult studies, demonology, artifacts of power, stuff like that, i mean hitler had scores of people studying this kinda thing. maybe as an aspect part of that whole apocalyptic war that pre-dates the game's setting involved a few of the supernatural nasties getting loose, i'm not talking about having an archaeologist suddenly flinging fireballs and lightning, i don't think that would fit...but an archeologist opening up an ancient tomb being thrown back a few feet because the tomb was cursed by the black magic of ancient egypt and he had the forethought to wear a "good luck charm" (aka talisman) to protect himself resulting in the throw back instead of him ending up dying mysteriously days later, i think could add some fun flavor for a bit of a reality that isn't always surface simple.
