This is Amphitrite, queen of the sea and wife of Poseidon. Despite who her husband is, she's plenty pleasant to be around. She saves most of her venom for him because he loves it. She's got her hubby's back all the way though, so no use trying to turn anything there.
She is about to arrive back in the city after being away for about six months for Reasons. I'd love to have some backstory with people and her. She used to be around for ages, after all, so she'll certainly have some friends about.
