The Disk of Quay was a religious artifact of the Weequay religion. It was tied to the Weequay moon god, Quay and was once kept in one of their grandest temples. The disk was made of metal and was covered in decorations. It was also inscribed with Weequay proverbs which were interpreted to be prophecies by those who followed the religion.

At some point, it came to be owned by Shiin's Library on Tatooine.
