Everything in this Universe is comprised of two opposite forces (Yin and Yang). The 2 forces are in a constant struggle within everything around us. When the forces reach harmony, the energy of life is created. The Universe already works harmoniously according to its own way and if someone exerts their will against that harmony he disrupts it, e.g. global warming affects the natural course of the seasons. Humans should be helping the Earth and nature to grow in its own way and cultivate the no-action and no-selfishness in order to allow nature to be itself. Yang (the light) does not exploit nature, but rather understands it, learns from it and treats it well. Yin (the dark) uses nature excessively, bringing disaster and possible extinction of humanity and Earth. This balance of harmony and creation of life is the main point I wish the game to bring across to players in hopes that they will learn from the experience and take more cognizance of the world around them.
