Just a thought...
I don't keep very good tabs on the kingdoms roleplaying forums (or in game things) but that's what gave me this idea... Some of you guys really like coming up with backstories for your characters, and post it on the forums...
But what if there were a way to integrate it within the game?
Have something set up where players can submit their own literary works to the server. Somebody would be set in charge of reviewing them and giving the okay, at which point they would be split up (If it's a long story) added into an item type, and put into shops. Probably a whole new shop to seperate them from the other books and scrolls.
The material could be completely unrelated to graal, just a story that a writer wants up and shared, or put as a history book.
Players could brush up on their GK history and hear about all the role playing going on.
