The Order Exposed - Underground Headquarters

Tonight Jim shared a video of he and Ian Q entering the London sewer network in St. James's Park. Ian Q mentions that he believes that there is a series of underground tunnels leading to The Order's headquarters. He is shown using the map shared last night.

In the video we see what Ian Q and Jim exploring an underground room that contain many artefacts, that lead us to believe that the chamber was indeed used by The Order. There is appears to be an early version of a Tesla coil, several laboratory flasks containing preservative fluid and soft tissue specimens, a set of knight's armour, a machinepistole, an arbalest repeating crossbow (also visible in Ian Q's first video), and a working version of the arc gun.
