And we will call her Femme Vitale
Unlike the Femme fatale who takes over a partner and drains them, this woman takes responsibility, acts as custodian for their partner.
This woman need not be a warrior for the purposes of this particular aspect. She does not need to be a goddess, or have any magical powers, as far as her quality of vitale is concerned.
She’s a woman with authority and the gravitas to exercise it within a particular type of relationship– one where she’s assumed responsibility for, and control of, a powerful partner.
There aren’t too many of these women in historic literature. There are a few in more modern lit– Abby Holland< the wife and partner of The Swamp Thing, has been suggested. In some ways, Eliza performs this function for Jack Shaftoe, (albeit at an enormous distance for most of the story)in the Baroque Cycle.
