Lost Artifact: Key to Room 000

Old tarnished room key
Item ID: #000-KEY
Status: Located near the service elevator, 2nd sub-basement.

Description:
A brass skeleton key affixed to a cracked ceramic fob labeled simply: "000". It bears signs of oxidation, as though submerged for years. 
The teeth are worn down in a pattern inconsistent with any known lock in the hotel. 

Provenance:
Guests occasionally report sightings of this key—always briefly, always misplaced afterward. One staff member insists it was once
issued to a guest during the 1939 centenary gala. No record supports this. The guest registry for that night is missing three pages.

Restrictions:
Guests are advised not to attempt to use the key. 
Staff have been instructed not to accept it at Reception, even if turned in.

        

Note: There is no Room 000. Except when there is.
