Zantorans resembled humans, though it was not known whether that was their true appearance or if they just had the ability to appear as humans.
The planet Zantor, with almost all of its inhabitants, was destroyed by a Garvak named Abel Crumpton. The genetic template of Zantor was saved in the Egg of Abundance. The last surviving Zantorans, Lettice Butts and Radcliff, recovered the Egg from Crumpton and planned to use it to seed a new planet. (PROSE: The Man from DOCTO(R))
