Sita is the youngest child of Stakar and Aleta. Born with latent psychic abilities, she was kidnapped by the Reavers of Arcturus and put under mind control by her grandfather, Ogord.
Under his control, Ogord used all three children against Starhawk, turning them into psychic vampires. When the Guardians of the Galaxy
removed them from the mind control, their powers reversed and instantly aged them into dust in mere seconds.
