On Shade the existence of glamours is highly debated, and many think it is no more than a figure of speech for a naturally charismatic person.
Someone with a glamour is believed to have a strong presence that makes others feel attracted, subordinate or fearful (depending on how they would normally react to the person).
Glamours, sometimes also called 'witchery', are said to be gifts from the fairies.
A 'glammer' is an archaic or dialectic word for a witch.
