Prescia Demorri is the Grand Shaper of Necronum, and is especially talented in weaving. Later on, it is revealed that she is the sister of Harmony Pemberton and the aunt to the five princesses. Despite her status as a Grand Shaper, she disapproves of the High King, Stafford Pemberton, and how he rules the Outskirts. As of book 4, she has assisted and become part of the Unseen.
She is very intelligent of her kingdom's shaping, and also very secretive. Since the staged death of her nieces, she has been even more distrustful of Stafford and stays particularly wary of outsiders.
