Tiphaine takes the two children to her castle, where she holds them. Rudi Mackenzie (son of Juniper Mackenzie and Mike Havel) is captured in a PPA raid to free Princess Mathilda Arminger, and Sandra entrusts him to Tiphaine. The remaining Protectorate forces regroup and retreat back to PPA territory. The Central Oregon Ranchers Association also pitches in, sending a few hundred light cavalrymen to help the MacKenzies break the siege of Mount Angel. While Corvallis refuses to help, two thousand Corvallis volunteers arrive to reinforce the Bearkillers and help them win their battle against Protectorate forces. Arminger divides his forces into three armies and dispatches them to destroy the three factions. Months later, Lord Protector Norman Arminger finally begins his war against the Bearkillers, Mount Angel, and Clan Mackenzie. At the Corvallis Faculty Senate, the governing body of Corvallis originally composed of professors from Oregon State University, the allied forces are unable to convince Corvallis to side against the PPA but they are successful in getting Corvallis to recognize the Dunedain Rangers.

Tiphaine successfully kills the knight and flees the scene even though she is ambushed by the Rangers. Sandra sends Tiphaine to kill the knight so he cannot be used as evidence against the PPA. Sandra Arminger and her servant/ assassin Tiphaine also travel to Corvallis to speak in defense of the PPA. Meanwhile, the Dunedain Rangers have captured a major knight of the PPA leading a band of raiders into their territory and take him to Corvallis for his trial.
