Essence (CofD)

Essence is the energy that permeats the Shadow and is the main currency and nutriment of the spirits.

Overview
Essence is born from Resonance in the world of flesh that ripples into the Shadow, similar to how a sound is produced when a bell is rung. Similar to oxygen, Essence is invisible even to most spirits, but it is nonetheless a vital component of the Shadows ecosystem. Resonances carry through to existent Essence, and even helps spawn more Essence. On places with a vivid Essence, a Locus can form that allows Essence to bleed into the material world.

Spirits are born from Essence motes and hunger for its to strengthen themselves. The Uratha, thanks to their half-spirit nature, utilize Essence to fuel their Gifts. Mages interact with it through the Spirit Arcanum, while some rites of Crúac are rumored to manipulate or generate Essence without the vampire really knowing what is going on. The God-Machine has speciliazed Angels that can interact with Essence and some of its fallen servants retain that ability.
