The three Weird Sisters met Macbeth and Banquo on the heath and pronounced their fatal prophecies that lead to the death of King Duncan. Afterward, seeing foes where he once saw friends, Macbeth called his henchmen and ordered the murder of Banquo and his son Fleance. The assassins failed in their mission, and the boy escaped their clutches. But what happened to Fleance and who were the kings the weird sisters referred to? As the Elizabethans apparently knew, Banquo was the ancestor of the Royal Stewart line, so no further explanation was necessary. However, Fleance's flight was only the beginning of a series of events that take you through the battle of Dunsinane, William the Conqueror's Normandy, the Battle of Hastings, and ultimately to Malcolm III's Scotland, where Fleance's descendant Walter became the first Steward of Scotland.
