Appears In: BoA
Race: Age 37
Koena was Gehn's acolyte on the 37th Age. However, as Gehn was fond of doing, he named Koena "Fah", or "One", rather than calling him by his birth name. Atrus befriended him during the time he spent on Age 37, and was surprised to discover that Koena no longer recognized him when he returned to the Age after Gehn's last revisions to its description, as the link had shifted to a new world that was similar, but not the same.
