Edgar Henderson, more commonly known as Edgar the Stubborn, is a Viking from the Stormchasers tribe and the father of Sigrid Henderson. Aptly named, Edgar is incredibly stubborn especially when it comes to change and Stormchaser tradition. Edgar has always wanted a son and was greatly disappointed when Sigrid turned out to be a girl and shunned her for most of her childhood. Edgar is a fierce warrior and trains the village boys in combat and dragon training. He is a close friend of Chief Armstrong and even arranged a marriage between Sigrid and the Chief's son, Baldr Armstrong. When Edgar discovered that Sigrid had defied tradition by learning swordsmanship, archery and dragon training - all activities that women were not allowed to learn - he became intent on persecuting her for her crimes.
