The whole "flood of darkness" thing doesn't make a lot of sense to me, tbh.
"Darkness" and "Void" are not supposed to be the same thing. Darkness is just another element like fire, water, light or wind. Void meanwhile isn't an aspect; it's the lack of all aspects. It's supposed to be some kind of entropic force that tries to reduce everything to nothing.
So if a flood of darkness turned the 13th into void, then how is a flood of light supposed to fix it?
