Xaktsesh is an arborist of Hellas on Mars. Like all Martians, she fled into the Dream-World when the plague destroyed their bodies. She also lost her pod-mate (husband) Kaxishek in the process, since he didn't follow the others, believing he was close to creating a body immune to the plague at his North Pole Lab. In Martian Dreams, she was depressed because her healing skills were useless in the Dream World, and she hoped he was successful. Later she left Mars in a robotronic body after Raxachk's defeat for Earth. She is probably still living on Earth.
