According to Moiraine, Anvaere doesn't care for anything except for horses and hawking. She also has a bad temper.
When Jarna Malari asks Moiraine if either of her sisters has a chance of claiming the Sun Throne after Laman is killed, Moiraine replies that that both of her sisters are well thought of, but not for the throne. She adds silently to herself that no one would trust Anvaere's temper on the throne. Moiraine says that no one will support Anvaere for the throne, even within House Damodred.
