Shado-Pan

The Shado-Pan, also known as the "Sword in the Shadows" and the "Watchers on the Wall", are a secretive organization of pandaren with a ninja-like culture dedicated to protecting Pandaria. The Shado-Pan are in a timeless struggle with the sha and the mantid. As Pandaria has no standing army, it falls to them to defend the land, so other pandaren can go about their peaceful lives.
