Quick Bio:
The Ethereal Queen, also known as the Iselia Queen or Iseria Queen, is a recurring hidden superboss. A Celestial being, she is often the most powerful enemy in the games she appears in, with exception of Star Ocean: Till the End of Time. She can only be fought after Gabriel Celeste is defeated, as his defeat is a pre-requisite for her to be found.
