Mystery Shack

You appear in a puff of smoke at the edge of a parking lot.  Nearby a sign reads "Bottomless Pit" with an arrow pointing away.  You can see down the road a dumpy-looking wooden building with a large sign on it. It reads, “MYSTERY HACK,” and you spot the S lower on the roof.

There is a small crowd assembled on the front porch of this building, with a gravelly-voiced old man yelling “Step right up to see wonders never before known to mankind! Only 20 bucks a pop for the most mysterious tour you’ll ever take! Step on up, people, the supernatural awaits you!”

Go take the tour.

Check out the bottomless pit.

Bill can go get his own key.
