Hello,
Although there is alot ofg good mods ou there ( Rus XIII beta version and Sword of damocles), it really is Prophesy of Pendor you wanna try out. There is a bit of fantasy in it, but no magic, dragons and such. Keep an eye out for this mod as well: http://forums.taleworlds.com/index.php/topic,67375.msg1741104.html#msg1741104
