Priscilla Farnese is a priestess of the religious Order of the Crest. She has the same family name as the late pope. Priscilla expresses her hope that she can help Lord Theo with, what she sees as, his "divine battle to subdue Chaos".

She has a 3-dimensional crest that she uses to heal people. When Siluca starts to voice a possible family connection, Priscilla politely silences her.
