Six Faces of Delusion

The Six Faces of Delusion was a headdress. It was created in the middle of the Sumaran Era. It had had five faces, with the wearer making up the six.

Ambril kept it in his museum on Manussa. He believed the legend surrounding the Six Faces of Delusion to be folly as it had only five faces. The Fifth Doctor instructed him to wear it, proving there were six. (DW: Snakedance)
