You arrive at The Whispering Marsh. It is especially the sound here that is special.

The silence is broken only by the croaking of frogs and the whistle of delicate little birds. You move along the footbridge into the tall reeds. Everywhere it oozes with life. A young woman lies on her stomach and tries to take some samples from the water. Another is standing next to it, holding a bag of test tubes.

As you get closer, the woman stands up and moves with a smile for you to pass.
