Each Green Lantern possesses a power ring that gives the user great control over the physical world as long as the wielder has sufficient willpower and strength to wield it. The ring is one of the most powerful weapons in the universe, and can be very dangerous. While the ring of the Golden Age Green Lantern (Alan Scott) was magically powered, the rings worn by all subsequent Lanterns were technological creations of the Guardians of the Universe, who granted such rings to worthy candidates. These individuals made up the intergalactic police force known as the Green Lantern Corps.

The Violet Lantern, aka Star Sapphire Corps Story:
The Star Sapphire come from Sector 1416 and comprise a Star Sapphire Corps whose purpose is to spread love throughout all 3600 sectors of the universe. The leaders of the Corps are Oans who, after migrating to Zamaron, found a parasitic crystal which they shaped into several Star Sapphires. These were used to empower females who had been loved and spurned, providing them the opportunity for revenge.

After realizing the power of the Star Sapphire was too great for them to control, the Zamarons forged a Violet Power Battery and power ring out of the Star Sapphire gem. Violet power rings are fueled by the emotion of love, one of the two emotions, with the other being rage, that most influence their user.

Not long after the initial realization of the Star Sapphire Corps existence it is revealed that they have built a Central Power Battery and have sent out rings not only to find those who have been loved and spurned but also those who have lost someone they love, with the intent to give love and fight against hate and fear. After the choice is made to become a member of the Corps, the initiate is encouraged to follow their heart.
