We need a new religion more than Riombara! We haven't had one for so long. Riombara had one but it fell apart a couple months ago :p
We totally do have a religion. And one of my dead chars is a god in it! (you can argue about the term "god" but I'm sure as hell sticking with that interpretation
) Check out the Order of the Golden Feather on the wiki, there's some interpretation about this but in my opinion it's pure ancestor worship which I think is awesome and very fitting for us, simple warrior-types.
Not that I'm against competition of a nice, well thought-out religion. I'm just not going to follow it until you make me a god!
