The Prince of the Ravens

From A Wheel of Time Wiki

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 raven's 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.

At the conclusion of the book Knife of Dreams, Mat Cauthon was given the title of Prince of the Ravens when Tuon completed the marriage ceremony between them.
