Chapter 9 · Wondrous Item

Void Glass

Effect
A lens formed from the boundary between the deepest Lower Realms and the total void. When held to the eye: any magical or divine effect within 30 feet becomes clearly visible as distinct threads and flows. Cannot be blocked by anything short of a Seal of Unmaking. Additionally: immune to illusions while actively looking through it, though only one eye is usable during use.
Uses
Permanent (passive while held to eye).

About

Looking through Void Glass for extended periods is disorienting. One scholar looked through it for three continuous hours and could not stop crying for a week, though she reported seeing nothing sad - only everything, perfectly clearly, all at once.
