They held parties on their private moon, one of which was attended by the Fourth Doctor. Facing criticism of their works, they withdrew them from the Pentaquoteque Gallery and exiled herself to her private retreat on the moon. Zhe used body augematation to change between genders and forms. In need of a muse, they created a sculpture with an AI persona, which in the process created a physical manifestation of their own self-doubt.

The Apprentice's forms became mutated and attacked the Tenth Doctor and Gabby Gonzalez when attempting to visit Zhe. Zhe was freed from her stasis and managed to contain the Apprentice. (COMIC: The Arts in Space)
