From the publisher's website:
As the incarnation of the Knights of the Round Table, you join forces against the game itself in an attempt to protect Camelot. Your victory hinges on the successful completion of legendary Quests, such as the search for Excalibur, the Holy Grail, or Lancelot's Armor; the tournament against the Black Knight; and numerous wars against the Saxons and Picts. But beware... all is not as it seems among these noble Knights. One of your number might yet turn out to be a traitor-in-waiting, biding his time while sowing havoc and destruction from the Shadows!
