Is it known where Calliope's hiding place (like with the stage etc) is located? and what exactly it is? It looks like what was left after Caliborn entered his session...

HER HIDING PLACE IS SOMEWHERE IN THE FURTHEST RING HIDDEN AWAY AND IT IS VERY ANNOYING AND HARD TO FIND.

IF ANYONE KNOWS WHERE EXACTLY IT IS LOCATED PLEASE TELL ME BECAUSE I LOST MY SISTER TO MURDER SOMETIME AGO AND WOULD LIKE TO SEE HER AGAIN. AND I DEFINITELY WOULDN’T HAVE HER DOUBLE KILLED AT ALL THAT IS NOT MY INTENTION I JUST MISS MY SISTER.
