This knowledge along with his knowledge of Sir Oliver's desire for glory enabled him to discover that Sir Oliver caused the fires by driving off the dragons so he could obtain the Ice Fire Shield to get rid of them and look like a hero. Knowing nobody would believe him due to the present hysteria, Jaxon resolved to protect the dragons himself by getting the Shield first and stopping Oliver. Sir Jaxon first appears after Sofia helps Sir Oliver out of the trap he set for him. Jaxon and Oliver fight a duel that Oliver wins through a cheap maneuver that Jaxon and Sofia both agree is a dirty trick. After he escapes from the imprisonment the trick put him in, Sir Oliver opens the dam and causes a flood. After Sofia rescues him, Sir Jaxon reveals to the young Princess Sir Oliver's deception and Sofia believes him because of Oliver's earlier dishonorable actions. Together, Sofia and Sir Jaxon defeat Sir Oliver and expose him to the King of Brazendell. After Oliver is banished, the King awards the Shield and the position of First Knight to Sir Jaxon.
