Ms. Kessler is the mysterious guidance counselor of the highschool that Alastor and Juniper attend known as Ashmere High. She is in her mid 40s or at least appears to be, she comes across as extremely enigmatic often speaking in riddles, showing up when strange things happen or speaking of things that most don't know about. She does give hints that she knows far more about mirrors, The Shift and even the 'Veil of Beyond' than most people seem to.
