Death Whistles, Terrifying instruments of religion and war, were used by Ancient Aztecs to summon spirits and create horror and fear wherever they went.
The scariest sound you've ever heard. These whistles emit a scream that sounds like a woman being tortured in horrible agony. Thousands of Aztec Warriors would use these to terrify enemy armies into dropping their weapons and running away in desperate fear. Aztec High Priests would use them to summon wind spirits, and control their populations with wonder & respect.
