The capsule is a GPS tag. The Chateau monitors and makes tracking information available to Masters. It's like being able to track family members on your cell phone. Without going into detail about the reason, I had a surgeon friend remove the first one. We destroyed it. It's somewhere under the Golden Gate Bridge in San Francisco. We were going to leave it out but after discussing the issue, Master decided to have a new one inserted.
