Hidden Passage

Exploration Stage: Atelier Delamode
From: Angelique
Description: The woman in the mask and cloak turned into a dead end t the edge of the fog. She stopped in front of the blockage obstructing the path, took out some object from her pocket, and then seemed to melt into the stones. I saw a similar object - it's a direction scanner, find it.
Completed: The woman in the mask and cloak used such a direction scanner to find a passage through the blockage, which was invisible to the eye. It took me a while, but I found the passage without this instrument and ended up in an unfamiliar place.
