While the game hasn't started yet and we have not yet burned characters, I did throw together a player's guide to help the players understand the world of Midnight. Here it is:
Player's Guide to Eredane
Feel free to comment if you think there is something unique about the Midnight Setting that I forgot to include. Keep in mind that the game is set in the late Third Age, before Izrador's final victory. The focus of the game is supposed to be on the slow, inevitable march of the shadow of Izrador across Eredane.
