Forbidden Methods

Exploration Stage: Octopus Citadel
From: Mr. Black
Description: I've known Violet for a long time, and I know when she is lying. She sometimes tries to manage her people in ruthless ways. You hear an unbearable sound coming from the interrogation room... examine the flower in the flowerpot there. This unpleasant sound seems to be coming from there.
Completed: Just as I thought. The sound is coming from a speaker inside this artificial flower. Violet is said to be using an illegal torture device! When this flower is placed in a cell, the sound is played from it all day long without a break, making it impossible for the prisoner to sleep. And finally, they succumb.
