The Key of Aratron is a key required to unlock the door marked "Aratron", which is in the Phaleg Hall in Nowhere.
It is located in the morgue in the west corridor of Nowhere, on the far wall behind a metal plate. Harry Mason needs to use the screwdriver, which can be found beside the pliers, to unscrew the plate and turn off the generator. This turns off the electricity that protects the key. If one examines it, the word "Aratron" is engraved on this key.
- The name "Aratron" is derived from the seven Olympian spirits. The spirits are often invoked in the occult, and are sometimes confused with archangels. In this case, "Aratron" refers to the Olympian spirit of Saturn.
