Editing Frost Faeries (section)

=== Glamour ===
They are regularly obscured by a glamor so that most mortals can neither hear them nor see their true forms. This appears to be a natural property of them. When inside of buildings built with iron, they become visible, which is another reason for them to avoid those structures.

Other ways to perceive the Frost Faeries are standing in the right place under the full moon, or to ingest a "secret drink", made out of many rare or disgusting ingredients, like certain bugshells ([https://en.wikipedia.org/wiki/Carmine E120]) and possibly parts of incense or processed fruit acids ([https://en.wikipedia.org/wiki/Sodium_benzoate E211]).<ref name="3.04" /> Humans [[Earthworlders|from Earth]] usually have eaten either the exact mixture, or just the right amount of those ingredients separately, which is why they are awakened to the activities of Frost Faeries.
