Greg Zhor

Origin
Greg Zohr is a member of copper-skinned The Rihns, a peaceful people descended from the aboriginal Martians and the first terrestrials from Earth to settle on Mars. Zohr rises to prominence due to his research in atomic energy.

The Rhins live in harmony with the pure-blooded humans until a mechanic named Karragon realized his ability to manipulate the people. Karragon becomes dictator of Mars, his followers are called Thelists. He encourages the Terrestrials to hatred against the Rhins. Greg is degraded to a test tube cleaner by egotistical Thelist scientists.

As Karragon gives a speech, Greg Zohr intends to use a ray projector to assassinate the tyrant from a nearby rooftop. Zohr's plans are halted by the appearance of Joan, Greg Zohr's secret paramour due to the oppressive atmosphere segregating Rhins from engaging in relationships with Terreristrials. She offers a compelling argument, suggesting to Greg Zohr he should direct his energies into secret work to design weapons to design Thelist forts and ships. Greg and Joan are discovered kissing by Thelist Storm Guards. Both he and Joan are captured.
