The Secret Garden
Site of the Royal Observatory, this location is under the control of the Brythonic Lodge and is close to one of their major nodes. The place is also used by the cabals of Shadow London to hold their Consilia. Sleeper staff are subjected to Effects to make them believe a private tour is underway and the building is shielded with a variety of wards.
A Certamen circle is located in a basement beneath the main amphitheatre. It is floored in black marble and etched with designs of silver.
