It is the custom in witchcraft to adopt a new name upon initiation. This reflects one’s new identity as a witch.
You may only disclose your craft name to other members of the coven. Certain covens have strict rules about disclosing craft names to outsiders.
The main reason for secrecy around craft names is is because of the power of names. It is believed that knowing the craft name of a witch gives a magical power over that person.
Many spells involve writing a persons name upon a piece of paper or object. Craft names tend to be individualistic in nature and may reflect heritage or aspirations.
You select a craft name through meditation, study or divination. Some are given craft names by the high priestess. Witches may also change their craft name as they advance in the levels.
