Outlawed? This sounds like a pretty serious problem. If all I.P.Ds are interconnected and they all start feeling negative emotions, wouldn't it be possible that all of them could spiral into an outbreak like what happened to you? Worse yet, the more revyateils that outbreak, wouldn't it be harder and harder to stop?

Why the hell would someone outlaw the way to fix a serious and potentially dangerous problem? Is the cure dangerous as well?
