ES

ES, or Essence, is a personal and non-renewable mystical ressource that each character is born with, and which is expended most often on performing permant magic, e.g. Enchanting a magical item, but Essence can also be sacrificed in other ways, and lost involuntarily. Essence is an in-world phenomenon, not metagame, and charaters can and should discuss it with each other, e.g.: "What did you spend your Essence on?" / "None of your business!".
