Energy is the main "currency" in the game.
But you can't own it. It's a dynamic flow.
It's main quality is lightness, which is defined by the direction of the flow:
All the energy flows all over the world is constant. If it disappears in one place, it appears in another one.
Feelings and weather systems are based on the energy flows of the creatures in that place.
Though and feeling particles are alive. Energy gravitates towards positive thoughts and feelings particles clusters. There is a natural energy flow from the areas of low concentration of positive particles to the higher concentrated regions in those. In the periods of rest when energy is not actively engaged a bad person would lose some energy over time. At the same time, a good person would gain it. For example, good people would wake up more energized. This makes bad people being incentivized to crave more energy.
Energy can be used to craft objects. It doesn’t consume energy to make an object. Once the object is dematerialized all the energy is returned to the creator. But materialization of objects requires high energy capacity and the max lightness.
