Yeah! So, as was said in that other thread...x3 there aren't any set religions! I mean, people are free to come up with their own as they like, and I do know that there are some religions that are being played out. For instance, an old player that left a while back created the Lumenari, a religious cult of fanatic sun worshippers who hail from a desert country and...like to cause a lot of trouble. Because they believe that they have to spread their faith and all--through any means necessary. 8D I play some characters from that! And there are characters all over that have various religions.
Oh! And then there's Necromantia. That's probably the only established location on the site that has a set religion, Libris Sanctus where they worship a Goddess of Death.
But yeah, you can create your own religions and stuff! I personally have always wanted to see more religious activity IC, just because...well...it makes for interesting plots. x3 Especially when you have the culture clashes like that, bwaha.
