The law and balance of the Equilibrium is a vital part of The Universe and anything beyond. It is in it's smallest explanation the balance of forces and energies. Whenever a creation or a destruction is done, it echoes in the Universe, supposedly resulting in a counter-reaction. If such a counter-reaction cannot happen, or one side of the Equilibrium causes a massive imbalance, energy is lost into a void. This void, once strong enough on it's own, will swallow existence as it is known.
