She is willowy and darkly beautiful.
She is one of the High Ladies sent to Cairhien.
She rides with Rand al'Thor when Rand's forces attack the invading Seanchan just outside Illian. When Rand is struck by an arrow and hits the ground, she rushes to his side with Ailil Riatin. It is unclear whether she means to help or kill Rand. Rand brings her back to Cairhien and gives her servants that are loyal to Rand and Dobraine Taborwin.
She disobeys Rand's orders and travels to Tear and is in the Stone of Tear when Rand arrives to talk to Darlin Sisnera. She and Weiramon managed to damage Darlin's attempt to settle with the siege of the Stone by sending their forces to attack, and die, fighting the renegade highlords, following the Shadow orders of letting the Lord of Chaos rule. Rand sends her with the rest of the Tairen forces into Arad Doman.
She greets Rand with King Darlin when Rand withdraws his forces from Arad Doman back into Tear.
After Rand's personal redemption, he seems to gain the ability to tell a Darkfriend by looking into their eyes. He orders all the High Lords and Ladies into a line and confirms Anaiyella and Weiramon as Darkfriends and sends them away as a warning to any others.
