The essence did not function as a simple reservoir of power, a gauge drained in bursts during combat or incantations. Nor did it regenerate with rest, nor was it measured in points or abstract units. The essence was the very fabric of being, a continuous thread woven from the first breath to the final heartbeat. It contained every word learned, every scar, every betrayal suffered or inflicted, every sunrise contemplated, every name loved. It was the living memory of flesh and spirit, inseparable from identity.
In an angel, it bore the resonance of the Creation's hymns, the echo of divine orders and the weight of centuries spent watching over worlds. In a demon, it rustled with silent rebellions, pacts sealed in shadows, the burns of the infernos and tears dried before they could even fall. In a mortal, more fragile, it was an intertwining of days too short, violent hopes and tenuous fears, yet just as complex and irreplaceable.
