Queen Sianna was one of the Ancient God-Queens, who made more a study ✣ of the technical workings of the Mirror system they had inherited than her sisters. She had three eyes, and formed glowing runes when using her powers. 5000 years ago, she and Albia were among a quartet of Queens attacked and effortlessly massacred by Lucrezia Mongfish; in a last desperate maneuver Sianna physically tossed Albia through the resident Mirror, immediately after which the system went dark. Thus, her final fate is unknown, but she is likely to be dead.
