The Insane Ghoul

The Insane Ghoul sends the adventurer to defeat a ghoul which has another item needed by Viktori.

Objectives
Retrieve Blind Mary's Looking Glass from the Insane Ghoul.
 * Mary's Looking Glass

Description
The looking glass was one of my finest treasures until. . .the incident. After that happened, I discarded it behind the barn. There was an Insane Ghoul who used to roam back there. Perhaps he picked it up. Rumor has it the devilish beast resides in the Tranquil Gardens Cemetery.

("Insane Ghoul: He carries the looking glass. Also, he is insane.")

Progress
I showed Cog the beginnings of our star-viewing machine. He was impressed. Did you happen to find a reflective device?

Completion
Most superb! This will work perfectly. Many thanks!
