Fiura
Feminine being from the mythologies of southern Chile. Wife of the Taruco, she dwells near forests and swamps, and is characterized by her ugliness and wickedness. Possessed of a horrible breath whose reach is notorious, she has a gaze that can twist the limbs of animals and people, and can even deform their features or cause all their hair to fall out.
The fiura also has the habit of bathing in crystal-clear waterfalls and emitting beautiful, enchanting sounds, by which she lures her victims.
According to other versions, the fiura can take possession of the will of human beings in order to abuse them sexually. Afterwards, her victims are left crippled (though satisfied).
