In-game description
"A gnome wizard named Perriavor found the constraints of the Prime Material Plane "too boring" and committed himself to visiting every plane of existence that he could uncover. Perriavor crafted these spectacles in order to see and interrogate beings from other planes, hoping in this way to find safe places in which to shift onto other planes. After speaking at length with a very pleasant and well-mannered devil, Perriavor followed the fiend's instructions for visiting Phlegethos, only to disappear with an anguished scream into a column of living flame. All that remained behind was a smoking pair of spectacles."
