sylvia (fate)
Member of Chaldea Security Organization, first appearing in the Part 2 prologue (but retroactively appearing in the anime adaptions of Babylonia and Solomon). She managed to escape the attack on Chaldea as one of the 11 survivors forming Novum Chaldea. She has not been seen since, but is presumably one of the off-screen personnel exclusively referred to with their surnames by Goredolf Musik.
