Zhe Ikiyuyu owned a moon that orbited around Ouloumos and was connected to it via a space elevator.
Zhe used the moon as a creative retreat for artists, writers and students. She also hosted parties that the Tenth Doctor remembered with delight.
He brought Gabby Gonzalez to this moon to meet Zhe, by which time Zhe had been in stasis for about a hundred years, and the moon was under the control of her apprentice. (COMIC: The Arts in Space)
After Zhe was freed from stasis, she reopened the moon, and Gabby stayed there to train her block transfer powers. (COMIC: The Good Companion)
