Amber Room

Origin
The Amber Room, referred in its time as the "Eigth Wonder of the World", was an exquisite room in the Catherine Palace near Saint Petersburg that was laid floor to ceiling in amber panels, gold filigree and mirrors that was crafted in the 18th century. During the Nazi occupation of Russia, the Room was looted and taken to Königsberg under the orders of Hitler himself. Following the Russian advancement in 1945, the Room was lost is the chaos of war and was never recovered.

A Warehouse agent managed to access the Room shortly before Russian forces reached it and secured the artifact using its key. The key was lost in the commotion and remains missing. Four people are known to be trapped by the artifact.

Effects
Created to allow safe escape for the Royal family in time of strife, the Amber Room is not truly a room, but a small container resembling a jewelry box. When a special key is inserted into the lock, the artifact overlays the room it is currently in, all living people being transported to the new space. Size does not seem to be an issue, and indeed the Amber Room has previously occupied what was once a pantry.

As long as the door remains unlocked, the Room remains open for anyone to come and go. If the key is inserted into the external lock, the Room retracts to its box state, taking anyone inside with it. Those in the box are kept in a chronostatic state, able to continue as if no time has passed once the artifact is reopened.

This feature was used on one occasion to smuggle a crowd of people out of hostile territory, no-one paying much attention to a lone man with a package. Currently the box contains four members of the Nazi party, who had attempted to use the Room as a safe-house at the time of collection. With the loss of the key, no-one seems in a hurry to let them out.
