As I said earlier, I think the subtlety of this story was ill served by appearing in a forum where people are looking for an overt scare.
To address some complaints about the story:
I think the tone of the story was perfect, if one reads Russian/Slavic literature, one finds this sort of understated dialogue and setting development everywhere. Moreover, there is a theme in post-soviet Eastern Bloc culture (any post-imperialist dictatorship, really) wherein there is often something shared but unstated about the past: massacres, 'disappearings,' droughts, food shortages, awful times where people did awful things just to get by. It appears both in literature and real life; profound experiences that are both defining and shameful that form unspoken bonds between people. The way they spoke of 'having the mark' flew under the radar for me as a sign of this sort of shared history, until about halfway through, when I realized it was much more of a 'mark of cain' sort of thing. It was a good use of context.
So far as the, 'if its a demon cult, just tell us its a demon cult' complaint goes...no. Respectfully, I think this attitude is a little simplistic. It misses out on the context of both the area and the concepts involved. Think Dracula, think old cursed bloodlines, think gods of harvest who require, ironically, virgin sacrifice. One notable thing that both of the younger (and perhaps the older, though he never gets the opportunity to show it) Radejastians show is a sort of strange sexual irresistability, one that I think is fairly clearly supernatural. Looking for demons -something obviously capital E Evil- misses the point. The Radejastians aren't death worshippers, they are life worshippers, with all the madness that can possibly encompass. Life can be a terrible and insane thing.This isn't a story about monolithic concepts of good and evil clashing, this is about the reality-subverting power of an alternate paradigm.
As for the main character being somehow passive; this story is his story, how he as a man severed from his homeland comes to reclaim a part of his past, however horrific. The end of the story is the moment of choice, the place where he is no longer being swept along.
