Faery

Faeries, or fae, are non-human, sapient, magical entities. Fae have unique powers depending on type. Dream pixies, for instance, can communicate to people through dreams and sense dreams even when someone is awake.

Fae have complex rules of etiquette. For instance, in The Hanged Man, when Rune lied by calling someone his friend, the pixie does not accuse him of lying but rather offers him "new information" as a politer way to call him out.
