Viking raids are increasing in the north so King Arthur sends Valiant, Gawain, Bryant, and Kay to meet with Duncan and go to tell them that their message of peace was received and accepted and Mordred was exiled once it was learned he was their ambassadors' murderer. But just before they are to leave with the ring as proof, someone steals it. Their journey is difficult but the arrival is worse since Mordred has arrived first and forged his own treaty with King Olaf claiming it was from Camelot, allowing him an easy chance to persuade Olaf to follow his own corruption of the New Order. Arthur has his own problems to deal with at home as ever more people blame immigrants for every crime and misfortune and insist of the banishment of every one. Written by

Was meant to air just prior to "A New Dawn" as the beginning of the final story arc, but was produced early then aired shortly afterwards. This resulted in the actual arc being the only one of the series which was played out in four rather than at least five episodes. The man who approaches Arthur complaining of an immigrant attack uses a different voice (like Llewelyn) and has no name, but resembles Allyn, who was officially introduced in "A New Dawn". See more
