You have to reject the council of crowns. Your Aide will approach you after that.
There is another ending if you don't join the council of crowns. It's not really a bad ending though. It would be cool to have nonhuman options!
It's just a little thing, but I would like the option to play as a queen. Also i think it would be nice to be able to name characters or if some of the characters like the Knight had names.
