As the story goes, the chief hunter of the tribe wanted to hunt an enormous "Choke" (a native ostrich) that he saw in the mountain. Just as the animal was nearly captured, it escaped flying toward the stars. The chief through his "Boleadoras" weapon with all this strength, but it didn't reach the enormous bird. Instead it got trapped in teh sky with the Stars, becoming Choke stars. This is how the Afra and Centauri stars were formed, the trapped "Boleadoras" of the bravest Mocovi hunter.
