They were founded on the myth of the green lantern corps which had ceased existence thousands of years ago. They knew of the energy rings, the location of the planet Oa
and the energy based powers that they wielded.
Creation Tomar Ro
of the Xudarian race found the location in space where the planet Oa once stood and from there used technology to create a siphon to harness that energy and rings that acted as transmitters for the siphon. The rings would give each member a narrow field of abilities but enough for them to use the myth of the corp effectively.
Life and works
The members initially presented themselves as heroes but later returned to crime. They battled the Legion Of Super-Heroes
and Green lanterns Kyle Rayner
and Cary Wren
before being defeated and placed in jail.
