Some time back in the olden days, you were a big fancy knight that held some land, after proving yourself able to hold ur little share, the king decides to give you one of his prized fortresses in the 'RdKham, or the land of ore.
Unfortunately for you, the neighbor Arabs and mercenaries are jealous of your big o'l pool of money making ore, so they're coming to get it.
Don't worry, the king heard just in time to send a large defending army, so ur not left with just ur little spear men and a couple of bows. Hopefully you can stop this fortress from being ransacked... again....
