The Emerald Herald is the old lady in the intro, and she was meant to be the "Ultimate Firekeeper" according to Aldia and his inhumane experiments. Shanalotte should've been able to kindle the flames how many times she wants, without having to sacrifice a powerful soul (Vendrick's soul), but the plan went wrong. I don't think Anastacia is the 4th Firekeeper because Drangleic isn't Lordran and DS1 is set eons past DS2. For myself It seems to be more logical that the Lost Sinner is the 4th Firekeeper.
