A has been involved with an organization that acts as a liaison between gods and monsters on earth, and has been romantically involved with Hades for several years now. They are engaged to be married. His family loves her and she is fond of them.
The pantheon has discovered that A is actually the human reincarnation of the lost goddess, Hera, and they want her back. Their goal is to raise Hera from within her human host, losing the host in the process - and despite having been on her side all these years, Hades has turned on her, siding with the other gods. She now has to fight not only for her own existence, but against a pantheon that has held this world (and others) in a stranglehold of oppression for eons - against everything she knows and trusted, and against the god who was her lover, supporter, and friend.
At least she doesn't have to do it alone. The human world isn't the only one the gods have been oppressing.
This could potentially go quite dark. I want to explore ALL OF THE ANGST. All of it. Ping me here or in the journal if any of this resonates.
