Keta (D'ni: Kehtah/[Keta]), originally named Leira but renamed by Gehn, was from a group of people known as the Amad — which is what the D'ni called those encountered on the Surface above the Great Cavern. After the downfall of the D'ni empire Anna and her son Gehn left the D'ni cavern. They settled on the surface in the Cleft, near where the Amad lived.
