The One and Nothingness, a Plotinian Imagination

Is there an empty set (nothigness itself) in the world of forms, the empty set and the One at opposite ends.
Or if one is the size of the set containing the empty set, does the One contain this nothingness?
If the One consists of nothingness alone does that mean the One is dependent on nothingness or on the empty set. Or does it mean that the One simply depend on nothing, except on its own being, on its own being as a set?
But if nothingness constitutes the one, everything that emanates from the one, emanates from nothingness, but where does this emanation end, does it end at nothing (but nothingness is within the one), so is there an aether in the world of ideas or space-dimension or the greeks' khaos. Nothingness emanates separating and annihilating this aether or khaos. And this is creation out of khaos?

Or is nothingness just the absence of the one, should nothingness depend on the existence of the one? Because nothingness is contingent and relies on the positive truth of the One? So does nothingness emanate from the One instead? Is nothigness the first aeon (in the gnostic/neoplatonic sense)? Is nothingness a demiurge subordinate to the One?
Or can nothingness depend on the One and one depend on nothingness, is this how the demiurgy of nothingness start? And all is derived from one? Or is nothingness and the One is one and the same? Are they two aspects of the same substance? Or are they a binarian entity sustaining one anothers' truth and existence.
