The histoy of Huiña-Huilli

There is a house by the Chambo River. A house with a sunken roof, broken windows, and roots creeping up its filthy walls. A man named Juan lives in this house. When girls walk by him he watches them with dark eyes and a sly smile. He calls after them, making them hurry on their way. Sometimes he approaches them, after which they shake with fear. In the village, parents warn their daughters not to walk by the river alone. They tell their daughters to be wary of the dangerous man who resides there.
On this particular night, a fog lies heavy over the village and the river. Juan is on his way home from the local tavern. He uses an old lantern to light the dark path. Suddenly, a girl emerges from the fog. He observes her as she shyly passes him by, her eyes fixed on the ground in front of her. A long braid runs down her back. Juan watches for a moment as it sways, and decides to follow her. The girl, noticing his nearing steps, starts running. Juan takes off after her, but although he is fast, the girl is faster. As he is struggling behind her the lantern slips from his hand and falls to the ground. A moment later the girl is swallowed by the fog. 
Accepting his defeat, Juan begins his walk back home, this time without a light to guide him. He walks slowly, careful not to trip in the darkness. After a while, a baby’s cry pierces through the dark. He follows the sound of desperate weeping. The sound gets closer and closer. He walks slowly until the sound seems to be right by his feet. Juan leans down and picks up a small bundle which stops screaming the second it reaches his bosom. He looks down at the baby in his arms, which is wrapped up in a blanket, covering its face. He moves the blanket, but instead of revealing a baby’s sweet face, he is met with the face of a horrible creature. Before he has time to react, the creature bites his finger. Shocked, he drops it to the ground.
-Why? Is all he can let out, his voice shaking.
-You are a bad man, says the creature before him. And for that I am going to kill you.
Upon hearing these words Juan faints. 
In the morning, Juan wakes up with his body against the cold, damp grass. The fog has cleared and he spots his house ahead. The memory of the creature from the night before comes back to him.
-It must have been Huiña-Huilli, it must have been. Juan mumbles to himself.
He had forgotten about Huiña-Huilli. He had forgotten the story that his grandparents used to tell his sisters. They used to warn his sisters about a spirit who punishes people that behave badly. Huiña-Huilli can appear at midday or at midnight. It can take the form of a baby or mimic its crying. It can bring bad energy upon its targets and make them sick, so sick that they might die. Huiña-Huilli teaches people to be good, and it makes those who do not learn the lesson disappear.
When Juan stands up to walk back home, he feels lighter than he has in a long time. He walks back home with an ease in his steps, an ease that he has not felt since he was a young boy. This feeling lingers in his body for days, months, years.
Now the house by the Chambo River is still a bit unkept, sure, but the man who lives there is a good man. He does not bother anyone. When girls walk past him he might give them a polite smile, but he would never dare to frighten them. Juan will never forget the story of Huiña-Huilli again.
