Febronia, also known as Feb, is introduced as a mysterious ghost or spirit. Febronia is no longer "alive", having been killed at her church on Miltia during the Miltian Conflict 14 years ago after being beaten to death with a metal rod, gored and eaten alive. However, her spirit and likeness return several times, due to being an existence of the Imaginary Number Domain of the Lower Domain who can only contact reality for a short period of time.
