Blackthorne's Guide to Magicians of the Ages

Also known as “the Wizarding World Who's Who” or WWWW, or Web (an inside joke among magicians).

A listing of dead magicians. The magicians are listed by name, but the order is neither alphabetical or chronological. A close enough study, or successful rolls from any number of skills, may reveal the pattern of arrangement. The magicians are listed according to their relative power or ability as sorcerers. Thus, the most powerful magicians are listed in front, with less-powerful mages taking up the final pages of the book. The book is a magical object, enchanted such that when a powerful magician dies, his name automatically appears in the book.

Along with the name is a biographical entry, detailing the magic practiced by the sorcerer, any schools or orders to which the mage belonged, and any awards or recognitions received. Teachers and disciples may also be listed. Additionally, any significant accomplishments will also be cataloged. The form of the entry is very much like the well-know Who's Who listings of the mundane world, thus the source of the joke.

Most copies of the book were lost or destroyed, leaving only three copies rumored to still exist by 1950. One copy belonging to the Thule Internationale disappeared during the Soviet War. The two remaining copies remain in private hands.

By 1965 the book is regarded as little more than a fantasy.
