This book was written by Badedas the Blue before his unfortunate demise.

I am afraid that I cannot let you read the book, after all, if I let you read through everything I have I would have nothing left to sell to you and it is most rare. However, I would recommend that you read the article on these people contained in the Musings of the Warlock, Volume Seven (Warlock Magazine Number 7 to some). For those articles and books which I am happy for you to browse through please ask me for my recommendations.
