A horror harem type role play

Basically I have an idea for a bit of a horror type role play but I'm not good at horror, I mean true horror like Steven King type horror is what I want. Mix in some harem, were the main person doesn't just end up falling for one but loves them all and such (if it's an gay or lesbian harem that'd make it even better). Not all of the harem would stay living they would die or be sacrificed for power or something too.

That is all for the idea I have like that.. so I'd just wanted to get this idea out there and see what people thought of it. I know a few people like horror but all talks of an group rp tends to die out... so lets try it again. I'm not a fan of horror role playing but that's because I've never done it... so I would need help for this type of role play.
