She shook her head. "No. But the descriptions given such as 'irritability' and 'emotional instability' do not do the symptoms justice. When I trained in this, a week after being exorcised, the retired master became so angry over a matter trivial that he became violent, and the efforts of many Stars were needed to subdue him. In his fury, he caused many injuries to others and in stopping him, the Stars caused many more to him -- so many that he perished as a result. This is not a fate uncommon, and this is why we conduct the training only using those Stars considered too old and too physically frail to serve."
