The Prince of the Ravens is a Seanchan title given to the husband of the Daughter of the Nine Moons. The title derives from the ravens' use as an emblem of the Seanchan Imperial family. It can be speculated that this title is also granted to any male member of the Seanchan Imperial family who stands in line to ascend the Crystal Throne. Alternatively, if a female were to be heir, the title might be changed to "Princess of the Ravens."
When Tuon Athaem Kore Paendrag completed the Seanchan marriage ceremony, Matrim Cauthon became the Prince of the Ravens. After Tuon was raised to become the new Empress of the Seanchan Empire, she continued to refer to Mat by that title, suggesting that this elite status will remain unchanged throughout his lifetime.
