Celtic Indicator

Exploration Stage: Observatory
From: Martha
Description: We don't have time to play around. We have to move quickly. Check the Observatory. I saw a rattleback somewhere. It's an elliptical frame with no bumps or corners. That's the indicator for the machine that will destroy the electrical anomaly.
Completed: You found "Rattleback." It can change the direction of rotation. This would help Isabelle create an opportunity to destroy the anomaly.
