I've thought about writing something, but it's not that easy to directly implement it into the game. Quests would help a lot, but we have to wait until Emps-Script is completely finished.
If it's only written in wiki, it will achieve nothing, since the average player doesn't even visit wiki. If a portion of our players can't even understand the simplest of English, how would you make them interested and able to read such fiction? We just don't have enough audience for it to pay off.
Also the question is if we're going to use RS lore or should we go for something unique. If it's the latter, it will not be that easy to do.
Fan fiction is probably the best way to start at the moment. That way we could see how many players are actually interested in it etc.
It's unlikely to happen though, since I'm not seeing many players who are up to the task and have the time and motivation to actually achieve something.
