Law of Flow
The Law of Flow simply states that if things do not move, specifically from one entity to another, the stagnation will cause all associated entities to suffer negative effects. It is often put as "What does not change, dies." The inverse effect of this law is that forcibly taking or hoarding these things will create a negative overabundance. The negativity often presents as "blight" effect surrounding but not necessarily effecting the hoarder. Another common effect is that of an uncontrolable singularity. This happens when the hoarding reaches a kind of critical mass. At that point, the hoarded thing draws in more and more of itself until it overwhelms the hoarder. While primarily applied to energy and magical effects, the Law of Flow also works for economic effects. This is seen frequently in social-level economic systems.
