I've actually fallen in love with the idea myself. The lore and history of the land is somewhat dependent on what sort of character you want to play. And myself. I'm very flexible. Usually, I like to be some sort of magic user, shape shifter, or mild magic wielding warrior. What little bit I have found out about myself is that the people is, at this point, very in tuned with the world they live in purely on the fact they have no other choice. Based on the fact that no one can truly rule the land unless they recover something lost mentions that they are very prideful and it could be purely superstition that prevents them from following an established monarchy. For all the people know the adventurer,s that seek to reclaim the fortress, find candy on the other side of the rainbow and think cavities are better than monarchies.
Personally, I have a hard time pre-planning too much these days because I get too excited and don't start the roleplay. I should ask, what do you see yourself getting out of it? I imagined that both parties [rolepalyers] will assume their own portion of history and intertwine them into, making a history and lore of the land together. If that doesn't work, we can still work things out. 8D
