This piece was created by the master conjurer as he was able to summon the Delphic Oracle to make this piece. There were many humans oracles on Earth, but they all represented the same underlying spirit and that was the spirit of the Oracle of Delphi. The Oracle of Delphi is the essence of time and the essence of fate. She can see both. She controls both. When you use this piece you will first need to calibrate it by asking yes or no questions such as "Is my name X" or "Am I X years old?" That way you will know which way is a yes swing and which way is a no swing.
You can ask this piece any yes or no question about your future and it will answer you. As you use this piece the energies in the pendulum will merge into your body and you will begin to receive full-blown visions of your future. You can also use the piece to see others' futures. If there is something you do not like about your future, communicate that with the oracle through thought projection and she will show you what to do and the path to take in order to change what you don't like.
