Kaylark took part in a "psycho-drama" designed to test the capabilities of Green Lantern Hal Jordan after his encounter with the wizard Myrwhydden. In the test, Kaylark posed as one of three Green Lanterns who overthrew the Guardians of the Universe in order to get advanced power rings. The prototype rings would have no weakness to yellow. During the psycho-drama, Kaylark appeared to have gone mad with power; seizing control of her home planet and installing herself as Queen.
