The Lost. Reports of Mordred's intentions to wage war against Arthur have reached Camelot, so the king has sent Sir Valiant to lead a small group in investigating the matter. The prince is completely dedicated to conducting himself properly on his first important mission as a knight (much to his friends' displeasure). So when Dennis is seriously injured while under his protection, Valiant throws caution to the wind in his efforts to save his young squire. This leads to some dangerous confrontations with two familiar faces and an unruly army of mercenaries.
