It's one of the witch's most important powers.
Glamor.
Glamorie, glamory, glamorye: n. The art (and craft) of making others see what you want them to see, and (by implication) think what you want them to think.
In common usage, the term implies “...making others see what isn't there.” “She's got him glammed,” we say.
But in fact, the term is neutral. Glamor can be the lie that tells the truth. Ask any artist. A painter can take a piece of stretched cloth and some paint and make you think that you're seeing a landscape.
If you want to learn glamor, watch those that are good at it: make-up artists, actors, demagogues.
As a storyteller myself, I can tell you for certain that narrative works a very powerful glamor.
This beat-up old knife may not look like much, but if I tell you that it was Sybil Leek's athame, well...it sure looks different than it did a few seconds ago. Glamor = resonance. In some ways, the history of the modern Craft is a glamor: a worldwide glamor now several million strong.
