Where are the human evidence in wolfquest?

I can't find it anywhere either, so someone has to improve this answer!

There is evidense in the northern mountains/hills in Multiplayer Mode in Slough Creek. Also by that tiny island there should be footprints and shoes. In the hills there is a sign and more footprints. Some people say they even found a 'human camp'. But no further evidense has been discovered of actual people roaming in the game.
