Delecta became the queen of the Kalpan System shortly after her father, King Deltar, died. Delecta's rule was challenged by Deltar's murderous half-sister, Ardora, who ruled the rogue planet of Myro. After Ardora brought the stranded Earthling, Lawrence Breck, to Kala for Delecta's coronation, Delecta began to develop feelings for the strange alien. She had her chief scientist, Telepan, help Larry to understand the Kalpan language. Later, Delecta accepted a duel to the death with Ardora in a spacefighter. During the battle, Ardora was killed, and Delecta held a contest to elect the next governor of the planet Myro. The post was eventually given to Larry, who was considered a hero throughout the Kalpan System.
