Shinjo Shono's Crystal Eye

Shinjo Shono's Crystal Eye is a nemuranai created by Moto Vordu. Vordu crafted it around 1156 while studying the City of Night. It is made of Night Crystal, a substance so far found only in the city.

Creation
Vordu made a deal with Shinjo Shono: Vordu would teach Shono ways to fight the Kolat, while Shono would submit himself to Vordu's experiments. Vordu put Shono to sleep and when Shono woke up his left eye had been replaced with one made of Night Crystal. Vordu wanted to replace Shono's right eye, as well, but Shono fled before Vordu could try. It is not known if Vordu had already made a second eye or if he planned to make it while Shono was out. If that is the case, there would exist a second, unused eye.

Powers
Shono's eye has several powers. Shono can now see in natural darkness, and can discern the true form of any shapeshifters or spirits that he sees. The eye glows green any time there is a Tsuno within 200 feet of his location, and Shono is much more combat-effective when fighting Tsuno. The eye has been growing more powerful with time and may grant new abilities as it does so.
