Chiloé, an island off the south of Chile, is said to be home to the Trauco, a sexually potent Dwarf with the power to paralyze women with a look, before having sex with them. The Trauco is described as being ugly and goblin-like, often wearing a hat and suit. His feet are stumps and he communicates through a series of grunts. Some reports suggest the Trauco doesnt even need to have intercourse with his victims, that he can, in fact, impregnate them with his gaze.

Often, when a single woman on Chiloé falls pregnant people assume the Trauco is the father. In these cases the women are considered blameless as the Trauco is said to be irresistible to women.

El Traucos wife, La Fiura, is said to be a grotesquely ugly dwarf with the ability to cast a sickness spell against anyone who rejects her sexual advances. Her breath is so foul it can physically scar a human and turn animals lame. Despite her appearance, she is generally irresistible to men and, after having intercourse with them, she drives them insane.

The Trauco is a mythical entity who inhabits the woods of Chiloé, an island in the south of Chile. It has a powerful magnetism that attracts young and middle-aged women. According to myth, the Trauco's wife is the wicked and ugly Fiura. The trauco carries a small stone-headed hatchet that he uses to strike trees in the forest to symbolize his sexual potency.
