I have some reading to do through this thread to see what has been suggested 

@Zran, Arguably a great idea depending on how in depth the OP wants to go with this, World building is a lot of fun, it's great fun actually- but for a one-time thread it can be overwhelming to work on all of that. However, if Dark wants to go for an Allaria/Apocalyptica-esque type deal where it's continually rebooted (and if we appeal to the almighty Mahz) it can eventually become a sub forum for a world to play in. 

I was wondering if there was room for an evil character? 

Ideas: I have an idea for a race- Shape shifters- name pending, cousin of the Fae. They're typically small 5'ish but there's always exceptions of course. As children they cycle through several different forms of their choosing but once they reach maturity they settle on their true form that they can shift into. One I'm eager to play of course. This of course is pending the answer to my first question. 

Pertaining to Deities, I was thinking of an "avatar" system for a character or two depending on your thoughts. An avatar of one of the chosen deities cannot change their allegiance once they've become an avatar, they're absolutely devout. They are gifted with certain abilities from their chosen god, respectively- nothing player responsibility would deem overpowered, and I think it would make for an interesting twist in the game. Hence my question about evil characters =P
