Oh hey look it’s my degree project. From Wikipedia:
“The Trauco, Trauko or Thrauco, according to the traditional Chilota mythology of Chiloé, is a mythical humanoid creature of small stature, with legs without feet, similar to a dwarf or goblin, who lives in the deep forests of Chiloé… The trauco carries a small stone-headed hatchet that he uses to strike trees in the forest to symbolize his sexual potency.
Whoever the Trauco choses will go to him, even if she is sleeping, and fall enraptured at his feet. No woman can resist his magical attraction; all have sex with him. Men of Chiloé fear the Trauco, as his gaze can be deadly.
When a single woman is pregnant and no one steps forward as the father, people assume that the Trauco is the father. Because the Trauco is irresistible, the woman is considered blameless. The Trauco is sometimes invoked to explain sudden or unwanted pregnancies, especially in unmarried women."
