Stitchpunk Talisman

The mysterious Talisman is a metallic object with three strange symbols etched on its surface, and plays a key role in the 9 universe. It is created by the Scientist, it requires an owner and a combination to activate it but if inserted into a socket of a Machine, then the Machine can use the talisman on its own will to kill anyone without doing a combination. The only true owner of the Talisman known so far is 9, since the Talisman was meant to be a gift to him from the Scientist to preserve life and human culture.
