that is not agnosticism Hydrolizer,
religious agnostics neither believe in nor disbelieve god. As such it is a terribly academic and dreary position
and while it may suit individual characters fine in the game or in real life, implementing it as an option is surely
the most boring category you could think of.
Mostly, I have met religious agnosticism in philosophers and scientists unable to subscribe to atheism
because theoretical notions alone do not warrant stronger version of atheism very well or at all.
[this does not contradict Joteses definition of agnosticism which seems to be in line with the above,
but we seem to disagree on whether this is an interesting addition to the positions you could take towards religion]
To add my own two cents, I like Hydrolizer's idea, I would just recommend to choose a different name,
like 'spiritual' position.
As he said, they would not deny the existence of the deities or disbelieve in magic, but they would,
(for a multitude of possible reasons) refuse to submit to any particular deity of the planeshift universe
and thus probably attract suspicion from all of them.

It would only be for those stubborn enough and willing to go the hard way, just as atheism is now...
