She is the ancient Mother Goddess who was deposed with the beginning of patriarchy and is now taking revenge (the protagonist's journal kinda sorta hints at this possibility).
"The Whole Truth" ending makes things even more convoluted: is Anna one of Angra Mainyu's forms? Is she his servant/spouse/daughter? Is she actually the good Ahura Mazda to Angra Mainyu's evil?
What is the meaning of the words "Sorry, I couldn't save you?"
Awesome Music: Say whatever you want about the game, but the soundtrack is great.
Epileptic Trees: Since the backstory of the game is not very clear, the players have nothing to do but make their own suggestions.
The movie
Overshadowed by Controversy: Luc Besson was hit with a multitude of sexual abuse accusations shortly before the film's intended release, causing the studio to shelve it for a year. Judging by its quick death at the box office, that wasn't long enough.
Unintentionally Unsympathetic: Although the viewer feels for Anna most of the time, the sheer callousness with which she treats Maude seriously detracts from her likeability. Maude fell for Anna the moment she first laid eyes on her, and they spent well over a year in a relationship that Maude obviously considered very serious, but to Anna she was never more than a tool, and she simply disappears from the story before the big showdown in the finale.
