The Eyes of the Dead are Exanimate Items. The eyes are collected by the minions of the Lich Lords from their slain foes. Only true undead can make the eyes through a special ritual.
The ritual consecrates the eyes of a slain enemy to bind them like the eyes of the true undead of a Cold Bargain, such that the Lich Lords can then see through them. It also can concentrate and enhance the magic of any that make use of them.
This enables the target to make use of the Eyes of the Dead. They have to remove one of their own eyes, and when they wish to draw upon the power of the eyes of the Dead, place it in the empty socket. The eye, once placed in a socket, will begin to decay and get opaque, at the end of 1 week it will dissolve.
One of the being’s eyes bulges out abnormally. The eye is glassy like the dead, but bloodshot and it seems to pulse with their heartbeat. A faint frost rings the eye socket, with wisps of frost-mist coming off of it giving it an even more eerie countenance. Even when looking direct at you, the eye seems unable to focus, and looks through you instead of at you. For just a moment, your blood runs cold and your scalp prickles.
While the true undead do not need this for the Lich Lords to see through their eyes, this can be done to the thralls that the Vampires, Ghouls, and Liches create as scouts and spies.
