About the book: year / Having talked in detail about the elven and human rings of power created by Sauron, Tolkien speaks very vaguely about what happened to the dwarven rings. In The Silmarillion, they are given about half a page, but this is an important part of the events associated with the rings of power. What were dwarf rings like? How did they perform? Why were they gone? This book is an attempt to answer these questions..
