Shadow Realm by Jordan-Tanker

In this game, you take the place of either Frank or Sarah. Your only memory is your name. You know nothing of your past. The only thing that you can see is darkness. But it's a darkness that seems to have a life of it's own. What shadowy secrets does it hold? You find out when you wake up to see a man with bad breath and a dirty beard standing over you, rambling about you stealing his sheep.
