Goodbye Silvia

You hold the logs together as you drift down the river. The rocking of the water is soothing and you find yourself in a deep, meditative calm. Time passes, but you're not sure how much. The sun went down at some point. Your calm is broken by a jolt of pain as your raft bashes into something solid. You raise your head up and realize you've ended up stuck against a strange stone and wood building. You are next to the shore, so you collect your belongings and climb off the raft. It immediately falls apart and goes down the dark river.

There is a big wheel being turned by the movement of the water. You've never seen anything like it. You circle the structure and find a solid wooden door into the building. There is a slight window in the door, and you can see light inside. The light grows, and eventually the door opens and you see the most bizarre thing you have ever seen before.

It is an orc. Only smaller than normal orcs. And instead of being pure white, it is the color of dried grass. It has no fangs. When it sees you, its eyes go wide and it starts to make frantic sing-song sounds. The door slams and you hear more sing-songs inside, from the first small orc and then from others you haven't seen yet inside.

What do you do now?
