Does anyone else think Cresent might be an alternate version of Athena? I mean, we find a Gothorita in Indriad/Vetus's mansion, and the records in the HoH indicate that Athena had black hair at one point.
This is super unfounded, but what if the final boss is the MC? Not us, but the in game character? Maybe after inhabiting someone else's mind for too long, the MC manages to "break free"?
