Instead of Humans taking over the world, it was animals, human-animal hybrids. No one knows how they came on this earth, but it's existed for thousands of years.

As a result, humans have developed the same traits as their animal counterparts. Lion-humans able to run and lead just like one, gorilla-humans as strong and humble as one, you get the point.

Put your self in a civilization. Be apart of the feline countries or Amphibians states. It is all up to you to live in the world where animals and humans are one in the same.
