What I might suggest instead is, instead of a thread where everyone has one post for their lore, why not have a single post with their most used characters and what faction they might be under and that's it? 

The way I see it, by building the multiverse around our characters instead of a preexisting story, we can free to create whatever we want, whenever we want, involving different factions and characters as we see fit. 

Wouldn't that be a little more fitting?
