Chesa is Egwene al'Vere's maid.
She has dark hair without a touch of gray. She is plump, pretty and stout. She is in her mid-thirties. 
She has a gray dress and darns socks.
When Egwene is raised to Amyrlyn Seat, Sheriam Bayanar finds Chesa and assigns her as Egwene's maid. During the Rebel Aes Sedai's march to Tar Valon, Chesa has her own tent. She is often present in meetings with Egwene and offers advice, but only as if talking to herself.
When Romanda Cassin and Lelaine Akashi find Meri and Selame to be Egwene's maids as well, they are forced to share Chesa's tent. When Egwene is captured by the Tower Aes Sedai, Chesa weeps often but keeps Egwene's tent neat.
