Lord Mavabwin is a Cairhienin noble.
Queen Elayne Trakand brings him and a small group of Cairhienin nobles to Caemlyn where she first demonstrates her newly created Dragons. He then witnesses Arymilla Marne, Elenia Sarand, and Naean Arawn have their lands and titles stripped by Elayne. These lands are offered to Bertome Saighan and Lorstrum Aesnan on the condition that they support her ascension to the Sun Throne. Mavabwn also offers his support in the hope of receiving some land as well.
