Item from The Wheel of Time by Robert Jordan
A gold ring shaped like a serpent eating its own tail — the mark of a woman who has reached the rank of Accepted in the White Tower, and the most recognized symbol of Aes Sedai authority.
The Great Serpent ring is the White Tower's most visible symbol — wearing one tells the world that you are trained in the One Power and backed by the authority of the Tower. For Aes Sedai, it's identity; for everyone else, it's a warning. The ring's serpent-eating-its-tail design echoes the Wheel of Time itself — cycles of death and rebirth, without beginning or end.
A gold ring fashioned as a serpent biting its own tail — the ouroboros. Every Accepted and Aes Sedai wears one. It's immediately recognizable across the Westlands and serves as both identification and warning.
