I'm definitely missing thread...
first : there's some files hidden in the vault.
Second, I don't remember where I saw it stated ( It might have been in the mailing list ) but basically there's Gods and Gods in Shadow World...
There's the Lords of Ohran and the Gods of Charon that are Universal Gods in the meaning that they are worshipped more or less worldwide and are konwn of worldwide.
And then there's the Local Gods... The Oracle of the Saurkurs, that tree over there, the river up here and so on... given enough time and enough worshipper said local god will appear and develop godly powers ( that is will be able to channel spells to its/his/her priests )...
So the Church of Rihand, if it has been there for several thousand years, venerating the same image might actually have created Rihand The ( Local ) God...
Now I won't even start to talk about a file called 'Religions of Kulthea' that has been laying unattended ( and absolutely unfinished ) on my hard disk for years, there's been snippets of it here and there in the forums...
