That’s where those terms come from, “astral energies” and “umbral energies” are not individual things, it’s a blanket term. Light and Dark are not elements, but they are energies…in a different sense. They are not elements, they are not of the elements, and they are not astral or umbral. It’s a different type of energy. You might see a Light and Dark sprite and think, oh, they must be elemetals, but those are made of an entirely different form of energy.
