Working with their science, the Psions created the many species of Vega's twenty-five worlds, subconsciously replicating their own origins. Active against them are the Omega Men, an interstellar group of rebels drawn from the Vegan worlds. Psion experiments accidentally created the Vegan goddess X'Hal. The Green Lantern Corps has been barred from entering or interfering within the Vegan star system due to an ancient pact with the Spider Guild. However, the fourth law of the rewritten book of Oa by the Guardians of the Universe states that the Vega System is no longer outside of Green Lantern Corps' jurisdiction.
