Getzor is a planet in the Mez'Dora Corridor of space. The inhabitants seem to be mostly Humans, although at least one family of Mole Men lives there as well. Although the general technology level is apparently low, the inhabitants seem to be accustomed to extraterrestrial visits.
Humphrey is an inhabitant of Getzor, living in a castle in the outskirts of a village.
Balzak Globotron and members of his crew visited Getzor, in a quest to visit Humphrey in his castle, and to find more clues as to Balzak's origin. (Balzak Globotron Series: Balzak Globotron)
