Glamour is an illusion/delusion power with multiple places of power.

Low levels of Glamour are used for avoiding or attracting interest. Medium levels amount to limited hypnotic effects; "Those aren't the people you're looking for." High levels let those with sufficient (great) Psyche advantages to do instant enthrallments.

Glamour is the power of the various kinds of Fae in shadow. Fae are Glamour-mutated humans (or nonhumans). Effects include vastly extended lifespans, jadedness verging on the sociopathic, and sterility. Hence the fae practice of stealing children.

Glamour is also used by some lesser unicorns and by some Lords of Chaos.

Experiments in Amber have shown that the ill effects of Glamour are negated by other powers, such as Shapeshifting (even the limited shapeshifting of weres and such) or Pattern. Andre took the plunge first and, after testing him for problems, Fiona, Florimel and possibly others have followed.

Glamour-sites look like big spheres of cloudy moonlight. They exert a very strong attraction on weres.
