Warden's Eye

An artificial eye that enables it's user to see through it. The original ones were created during Mormo's reign, but modern arcanists could reverse-engineer the artifact and were able to craft weaker versions with some more limitations.

Mechanics
A creature attuned to it can concentrate and see through the artifact as if they would see through a normal eye, similar to using the Clairvoyance spell. Two eyes can simultaneously attune to one Warden's Eye. It doesn't matter if those eyes belong to a single creature or to multiple or if those eyes are still functional or blind.
