Ancient Embroidery

Exploration Stage: Sunny Terrace
From: Martha
Description: The stone enveloping the box is the same stone that covered the troll due to the sun. This material is woven from negative energy. During the ritual, I will destroy it with a shisha pendant. Can you find it for me?
Completed: You don't really think I sent you for a simple mirror with colored patterns, do you? Shisha is an ancient Indian embroidery technique. The bright threads around this mirror symbolize the rays that will destroy the negative energy around the petrified box.
