King Arthur is often seen as a figure of myth - surrounded by shining knights, devious wizards and magic swords, yet the legends of King Arthur may have some historical basis. This supplement delves into the historical sources for Arthur and provides all the rules and army lists you need to field a heroic British force defending against the depredations of the Saxons, Picts, Scots and Irish in the Dark Ages. The heroes and villains who populated the legends are also featured, allowing you to muster your favourite Arthurian characters ion the battlefield. Scenarios for Arthurs twelve battles are detailed, as well as his final fight at Camlann where he faced his nemesis, Mordred. A campaign system allows you to play these as a single narrative, with options to play Arthur in a Welsh, Northern, Southern or pan-British context. An additional campaign brings to the table top the action described in Geoffrey of Monmouths spurious history of Arthur, whose victories culminated in the mass battle of Siesia, where Arthur and his allies faced off against the might of Rome and her allies in the East.
