Behind the scenes
The are a supposed group of people found in India. They were said to have backwards facing feet, but this didn't stop them from running quickly. They were said to live alongside wild animals and their supposed savagery made it extremely hard to capture them. Supposedly, they were only able to breathe the air in their home valleys, preventing them from being captured and taken anywhere else.
