The Touchstone of Ra (object)

The Touchstone of Ra is a object that when united with four other ones, can make the Pyramid of Ra, but only after a human sacrifice. This object plays a big role in the Season 3 movie, The Touchstone of Ra, when Sophia Danae comes to the school as a pre-freshman, but soon, her intentions are revealed as she tries to find the other four pieces to be able to create the pyramid of Ra.

History
The touchstone has been passed around for a long time. It is known that Robert Frobisher-Smythe had once owned the object, and had also gotten the other four. He buried the other four in the foundation of the house, and then sent the touchstone away where it eventually ended up at a history museum.

During a visit to the museum by the Anubis House students, one of the future Anubis residents by the name of Sophia Danae stole the touchstone from where it was and planted it in Eddie Miller's bag, to make it look like he stole it. During a bag search later that day, Eddie tried to hide it but was eventually caught. The touchstone was taken by Victor Rodenmaar Jr., but it was stolen back by Eddie. Eddie kept it locked under his bed in a box, but Sophia found out and stole the touchstone once more.

It is learned during the middle of the movie that whoever has touched the touchstone will turn to stone once a sacrifice is made and the pyramid is built. It is also discovered that the touchstone can be used for mind control and also can be used to bring forth the pieces of the pyramid from wherever they hide.

In the climax of the movie, the pyramid is assembled by Sophia despite Sibuna's best efforts to stop her. Also, Mara Jaffray puts on the symbol of Ra because of the Valedictorian medal she gets, and she goes to where the pyramid is to offer herself as a sacrifice, while not under her own will. Eddie, however, learns from Victor that he must sacrifice himself, since he is the Osirian. He does try to, but only his powers disappear, and Eddie lives.

Victor leaves Anubis House with the touchstone to make sure that nobody can ever try to reassemble the pyramid.
