Necrosians: Undead Martian Misfits who need to absorb Life Essence in order to maintain sentience. The Necrosians are former servants of the Killers of the Red Sand. They began as the people of Old Earth who perished in the Midnight Massacre, thousands of years ago.  The Killers resurrected and recreated them in their own twisted image.

The Necrosians are not quite alive and not yet dead. Their goal is to gain access to the Core so they can cure their insatiable lust for energy and return to being whole. Because of their past affiliation with the Killers, they are reviled throughout the galaxy. They are trying to rehabilitate their image by doing good deeds and using their curse for good(?)

Powers: Energy Absorption, Doesn’t Require Sleep, Building. And whatever abilities they had while they were still alive.
