Key of Ophiel

The Key of Ophiel is a key required to unlock the door marked "Ophiel" in the main hallway in Nowhere and, in turn, allows Harry to continue into the depths of Nowhere. It can be found stuck in the faucet in the shower room by the elevator. To remove it, Harry Mason needs to use a pair of pliers. Engraved upon this key is the word "Ophiel".

Trivia

 * The name "Ophiel" is derived from the seven Olympian spirits. The spirits are often invoked in the occult, and are sometimes confused with archangels. In this case, "Ophiel" refers to the Olympian spirit of Mercury.
