so does Light also represent universal truths/facts? if that's true then couldnt a Witch of Light or Heir manipulate what is true (like gravity pulling things down). Meanwhile a Maid or Sylph of Light would add existing truths to what is already true (like yeah gravity pulls things down but now it also intermediately liquefies anything that it's pull gets stronger on). Sorry if Im mistaken, I'm a little confused on everything Light encompasses
Rather than the facts of reality themselves, I’d say it is the spread of said information- For reality alteration though, Space or Time can be two good bets. But who knows really.
