Star Sapphire is the name of several fictional characters in DC Comics; many of them are villainous, and all connected in origin. Within DC continuity, an immortal race of warrior women (the Zamarons) were depicted as having the ancient tradition of choosing physically identical mortals from across the cosmos to serve as the host body for their queen. The woman chosen to serve this queen is called Star Sapphire. She is given the queen's symbolic weapon: a crystal resembling an actual star sapphire that grants the user powers similar to the power ring of Green Lanterns.
Kyle Rayner is recruited into the intergalactic police force Green Lantern Corps, under the tutelage of Hal Jordan, veteran of 40 years, and John Stewart, veteran of 15 years. Together, they must combat a galaxy-wide conspiracy centuries in the making.
