During Kelson's coronation the following morning, Charissa appears and challenges the prince to a Duel Arcane, an ancient form of magical combat. Morgan attempts to answer the challenge in his role as King's Champion, but Charissa's own champion seriously wounds the Deryni duke before being defeated, leaving Morgan unable to deal with Charissa herself. However, seeing her son's danger, Jehana attacks Charissa with magic, revealing that her fanatical hatred of Deryni has concealed her own Deryni heritage. Nonetheless, Charissa easily defeats Jehana, and Kelson is forced to personally duel with the sorceress. As the combat is about to begin, Kelson suddenly unravels the last of his father's clues and activates his own powers. Using both his Haldane powers and his newly discovered Deryni heritage, Kelson manages to defeat Charissa. With the Pretender now dead, Kelson is crowned as King of Gwynedd.
