Desna and Eska are the twin son and daughter of Chief Unalaq, as well as his successors as leader of the Northern Water Tribe, and cousins of Avatar Korra. They were initially very loyal to their father, heeding his every order, until he used the energy of Harmonic Convergence to become the Dark Avatar. Realizing that their father was beyond salvation, they turned against him and helped Team Avatar to save the world from an era of darkness.[7]
As chiefs of the Northern Water Tribe, they oversaw various social and legal reforms,[8] and took part in diplomatic efforts to stabilize the Earth Kingdom after the murder of Hou-Ting.[9]
