The counterpart to this series is the Forest Ring. The forest also protects and moulds, but by its own means and in its own way. As a green lung, it is jointly responsible for the survival of all life on earth and draws its strength from the water through which it can grow. Beneath the green of the tourmaline, the forest emerges surrounded by wood that turns into earth. As with the Ocean Ring, there are several levels that reveal new details and stories through the inside and outside.
