Well I know nothing of Europe but this seems fairly like what I've heard and seen in visits. That goes the same for the Oxford and black metal concert scenes. But it at least seems like you know what you're doing, which is every writer's initial goal. However, the issue of cult and Christianity- which I assume is going to be among the most important themes of this story- might be harder to pull off. So far, you've got a good grip on it, and it fits the beginning well, as well as the characters' situations. Considering the vast majority of this network's writers are hoplessly athiest, quite frankly it's not going to bother many readers at all if you make a few innocent errors (it will only further their unbelief). On the otherhand, there are those who will be bothered. As a writer, you shouldn't be influenced by the fans or critics when they go against your own beliefs, so my advice would be to make it clear (maybe not initially, but sometime) where you stand on the themes of your work and why you're writing this. Of course, this is just the first part and not nearly enough to make any conclusions, but readers will either be interested or offended- both of which you should want. Just make sure you keep their curiosity long enough to make your point. Otherwise, this potentially promising, cautious story will just become another roaming stranger's opinion. Leave an impression, yes, but impacts are more memorable, especially when playing with incredibly powerful themes.
