    of the game is to get off this weird place and transport yourself back to

      You appeared in a dark cellar. The last thing you remember is that
      you were drinking an invisibility potion from your family wizard Crook
      in order to hide before curious tourists on fiddle feast. The old Crook
      must have mistaken it. It seems the potion teleported you to some
      strange unfamiliar place instead of simply rendering you invisible. Now
      you need to find a way back home.
