Gave my characters complex relationship with their pronouns and gender identities. Some of them get frequently misgendered in the story, others have pronouns purely based on how they are perceived. Some transitioned later, some earlier.. some not at all.
A few of the followers use it because of fallen. With the exception of Marty (who does not accept it at all and has made this very clear to him), Cassie (who love love LOVES being an it) and Lawrence (who would not let anyone else call him this, and it is thusly not listed for him) the rest accept it because they love Fallen. Corvina rolls with whatever they are seen as, which never is the full truth. They just want to be acknowledged. Sylvan probably wouldn't have transitioned at all without fallen's presence.
Fallen himself technically had no pronouns nor gender.. not even a name untill he was gendered as a man. It takes a special kind of creature to be above the genders society lays out and come back around to actively weaponizing the societal oppression to your advantage.
