The Warhammer army books each include the rules for several Special Characters within their pages. They are famous, named war leaders and mighty mages, tales of whose legendary (or nefarious) deeds have travelled far and wide, such as the Emperor Karl Franz, Grom the Paunch of Misty Mountain, the infamous Vampire Lord Vlad von Carstein and many more besides.
Special Characters are exceptional individuals but, more importantly for our army selection purposes, they are unique – each can be included in an army only once.
