The chapters have no coherence, at all. Because they are separate articles, and they are not published, they are just backup copies of scattered articles.
Those who want to read the article, especially those who have read "Amethyst" should not enter, in case the ending is misled.
If you haven't seen it, it's best not to enter, because there are many pits that are thousands of years old. This book is not for the purpose of publication, it is just for reference.
Sorry
