Tomas is probably a fake name of an anonymous Castanedian author who has written two fine books. In my oppinion the only true Castanedian author who is not directly associated with Castaneda. His book 'The Promise of Power' contains a large crossreference of Castanedas work with almost ten thousand references. His other book, 'Creative Victory', contains poetic affirmations for 'the warrior who rests', which is what he calls the practitioner who saves and conserves energy.

Victor Sanchez
A Castaneda influented author and practitioner who has  written two books. He is not, however, strictly castanedian. Very interesting books, the first one, 'Teachings of don Carlos', contains alot of practical aspects of Castanedas teachings, especially on saving energy. He has got a webpage somewhere.

Ken Eagle Feather
Claims to have been taught by don Juan, although he says that his teacher never stated his name. He describes alot of his own experiences, mostly dreaming, and his books have some interesting stuff.

Marilyn Tunneshende
She is known to have been interrupting Castanedas public seminars claiming to be the 'real nagual woman'. Some info about her is available on the net, both interviews and pages she have made herself.

Margaret Evelyn Runyan Castaneda
Former 'wife' of Castaneda. She have written a book about her life with Castaneda before he met don Juan, "A Magical Journey with Carlos Castaneda". May be of some interest if you wish to know something about the person Carlos Castaneda, which I don't. Castaneda (or Cleargreen Inc) have issued a lawsuit against her for publishing this book.
