A Signal to an End

Exploration Stage: Abandoned Factory
From: Dr. Barry
Description: The negotiations between Vera and the League were long and productive, which is why Vera’s betrayal hurt so much. Stealing developments... It all happened when we heard a terrible noise coming from nearby. It came from a device called the Screaming Cube. Take a look at it.
Completed: See all the speakers on the Screaming Cube? They made all kinds of sounds - roars, screams, growls. The noise interrupted the negotiations, and we all ran out into the street. We found the cube quickly, but the developments had already disappeared. I’m sure that it was Vera who planned and committed the theft!
