What if humans didn't inhabit the earth anymore?
What if they were shifters that lived in groups large enough to be a city or small enough to inhabit a large ranch?
What if it was just like the mustang's life system when there is a top male and the rest of the males followed his orders and helped him with protecting the females when needed?
What if they were horse shifters that followed the ways of the American mustang because that's how they were forced to live when humans were on earth?
