A Cour'souvra is a device used to control a person who can channel. It is constructed of crystal and wire. When a channeler is mindtrapped, their soul is linked with the Cour'souvra. A channeler can only be mindtrapped in Shayol Ghul due to the malleability of reality there. To create the Cour'souvra, a channeler is given a small cut on the ear, and has their tongue scraped with the same knife. The blood and saliva is then scraped into the empty Cour'souvra, and it is thrown into the Pit of Doom. The mindtrapped channeler can sense the holder of their Cour'souvra, and when it is being used. Crushing the wire cage of the Cour'souvra isolates the mindtrapped person's soul inside the gem, destroying their free will and leaving their body a mindless automaton; this threat gives the holder of the Cour'souvra effectively complete control over the victim.
