Master Kaecilius is no longer on the side of angels.
After stealing a book from the Kamar-Taj library, Kaecilius and his acolytes exit a building and are suddenly in a street. They come out of a doorway the corner of Whitehall Ct. and Whitehall Pl., and head west on Whitehall Place, London.
They are chased by the Ancient One who confronts Kaecilius and his acolytes on Great Scotland Yard near Northumberland Ave.
