I hadn't considered the subject yet. There are at least two other religions that are going to play an important part in the game, and I'm pretty sure one of them wouldn't give a sard about incest. That being said, they probably wouldn't give a sard about anything else other than worshipping that which lurks beyond the Starry Veil.
I personally don't mind that, as it actually feels good to know that there are people interested enough in the game to ask about it. That being said, I understand why it can be viewed as a bad thing.
Let's hope this isn't the case here.
Thank you very much for the reports! I fixed them, but I'll probably wait a bit before uploading it.
I'm currently working on a huge update that will probably appear within the week.
Again, thanks everyone!
