Go to the shepherds. Leave and record the draft when they disappear (invisibility). Go to the right end of the Crystal Palace (on the OUTSIDE) near the hemisphere and weave an invisibility draft on the workers in the tower. Then go in the base of the tower, enter the crystal and double click on it. Do it again after you've listened to the talking men. Double-click on the scythe and record the draft (sharpen). Cross over to the left of the workers and double-click on that bell. Look into the sphere and record the draft (terror). Double-click on the bell, go to the right of the workers, double-click on that bell, and return to the shepherds. Weave the terror draft on them.

Nothing. It's just a red herring. You can fill and empty it to your heart's content, though.

You must weave the invisibility draft on the workers from outside the tower.
