Magic: Syrene is possibly one of the most powerful sorcerer's in existence.
Syrene is a sorcerer from more than one million years in the future, when human society has reverted to a medieval-mystical world in which she and her father Ambra ruled Earth.
When Lord Satanis sought a mystic runestone of Merlin that was the source of Ambra's powers, he raised a revolt against Ambra and killed him. However, Ambra hurled the runestone magically through time, beyond the reach of Satanis or Syrene. Rather than wasting their energies fighting each other, Syrene and Satanis agreed to marry and rule Earth together. But they planned behind each other's back to seek a way to follow the runestone through time.
Finally, both found the right spell and located the runestone to the 20th century. But in order to to gain its power it was necessary to filter the energy through an invulnerable body. They sought out Superman.
