What magical object in literature can control people?

Kelloggs: What magical object in literature can control people?
What is a magical or scientific object made up that can mind control people? Like the Silver Chair in Chronicles of Narnia that controls Prince Caspian. In manga, television, literature, comics, anywhere. Any come to mind? Thanks.
I should say fictional examples of mind control.

Sodium thiopental (Sodium pentothal) has a reputation as a truth serum. It really just makes someone more relaxed and more willing to give into pressure, as it weakens the person’s will. This can be very useful in controlling someone.

Minor correction: it was Prince Rilian, son of Prince Caspian 10, who had his mind controlled in ‘The Silver Chair.’
