Lisanne

Lisanne was the guardian angel of a priestess named Sister Lavaine and the only angel in history known to have become mortal.

Her name was immortalised through the now-discontinued Crown of Lisanne artefact and she, along with her sworn priestess Sister Lavaine, were subjects of the tome titled A Booke of Hystorickal Seraphs, or Angeles of Olde, authored by Arisa Raviede.
