Glass Eye of Qaliq

The Glass Eye of Qaliq was a glass eye imbued with magical powers. Once it was put as replacement for a lost eye, the individual could not completely die. The head remained alive, able to look, breat, and even speak.

Aziz
Hisham the healer put it to Aziz, who was devoured by ghuls. His head lived and floated in the water until Nim retrieved the artifact upon Aziz's request.
