Glamour

All Faeries have some degree of transformation magic, known as glamour. At minimum it is what shows and hides their wings. Beyond that it can disguise features, grant temporary physical traits, and — at real power — take on an entirely different form.

Goblin glamour is weaker and cruder, tending toward frights and false faces rather than beauty. This is treated at court as further evidence of a lower nature, rather than as a different specialization of the same art.

Passing

Faeries have been known to hide among the non-Faerie races with this magic, though some of those races are far better at sniffing them out than the Faeries expect. Hobgoblins in the Waking World rely on a related trick, and cats — see the same page — defeat all of it.

The Weakness

Maintaining a glamour requires sustained concentration and mental effort, which Faeries are not naturally gifted at. The reliable way to smoke out a disguised Faerie is to tax their attention: distractions, sudden environmental changes, or a complex task that divides their focus. Once concentration wavers, the glamour falters and the true form shows through.

Spriggan shadow-work is the one attuned magic that regularly beats a glamour at its own game, and Wisps are the race least able to use one, since masking their own light is the hardest thing most of them ever attempt.
