Theories about the Ghost:
Theory One: She is the ghost of a priestess of the Temple. I have 3 ideas for possible identity.
1) Sister Theressa: the creator of the Enhanced Fertility potions. Perhaps her unfinished work kept her bound here? She could mabey teach MC how to create new, weirder sex potions & perhaps make it possible to have sex with/knock up a ghost
.
2) The previous High Priestess of the Temple.
3) A generic/unkown priestess that MC has no prior knowledge of. (In my opinion least likley unless u see theory 3)
Theory Two: She is not a ghost at all & is in fact an astral projection Qetesh herself. Manifesting to MC now that she is getting her power back.
Theory Three: She is MC's mother. Her status of living has never actualy been confirmed. Perhaps MC's mother was an acolyte/priestess of the Temple who died during the Goblin War (this could link back to both Theories 1 & even 2, if the rumour that Qetesh is MC's mother is true- DO NOT TAKE THAT AS GOSPEL. It's not been confirmed or denied as far as I'm aware)
