The Cloaken Book of Anti-Magic

The Cloaken Monks were the original guardians of peace and justice in the Kingdom. One of their core
beliefs was their hatred of magic. While the Monks admit magic is real, they insist all magic, and those who use it, are evil. The Monks compare magic to a flame. The flame must have a source of fuel, which in the case of magic is evil. As magic is used, the evil consumes the person (their soul), eventually leaving only worthless ash and suit. 

In their desire to eliminate magic, the Monks recorded every known method to counteract magic. The book, known simply as the Cloaken Book of Anti-Magic, contained counter potions, a list of weapons which could be used against a wizard and how to make them, and also gave details on how to deal with and avoid magical creatures. 

One chapter of the book contained detailed instructions on how to identify a witch. This was considered critical since most witches operated in secret or more often as members of a secret coven. Wizards were much more open with their magic and rarely hid their power or association with wizardry. 

It should be noted that Cloaken Monks would openly use potions either to heal or to ward off evil. They considered any potion that required an accompanying spell or incantation to be magic and therefore forbidden. If no spell or incantation were required, the Monks considered the potion to be scientific and was therefore allowed. This included many medicinal concoctions that had been in use for centuries.  

Small, pocket sized, versions of the anti-magic book were produced and carried by senior Monks. Given the expense and difficulty involved in duplicating these texts, possessing one was considered a high honor.
