It's not all about Professor Tolkien's view as it was captured to that critical point when he died. There is more to this than meets the eye. In part, it's also about where the imagination roams when one reviews the mythology and looks at Arda as the meandering river of wishful thinking takes you--'what would it have taken for the Two Trees to have survived" "why couldn't they figure out how to work with Melkor". Having said that--consider what my work does extend--and where speculation does have a place, and what we cannot know, is what principles of care would go into the Second Making.

The Second Prophesy of Mandos hints at a number of ideas.. We know from Tolkien's divisionist thinking in how he bifurcated good and evil that there were numerous points of great suffering in Arda caused by Melkorian and Sauronic thinking. Sauron's Necromancy (and how he made Spiritual Planes of unlife, death, fear an life-bleeding) are, I would expect, rents in reality fabric that would be attended to in the Second Making.

My adaptation of the terms unsight, unlife and so on, are just extensions of what Tolkien did do so prolifically. Ungoliant's unlight (was not just darkness). Feanor and Galadriel as unfriends. Ungoliant is another tantalising hint at what rents in reality and metaphysical planes Melkor's monsters made. Unlight was some kind of syphoning of light, or some kind of event horizon where things were, once drawn into, were lost for all of time. Presumably, for example, Ungoliant swelled from the gobbling up of the Light of Teleperion and Laurelin and that she holds or houses something in that bottomless well waiting to be -- inversely manifested and flushed right on out. To put this another way, if an inverse of a 'good' thing is an 'evil' thing, then what's an inverse of an already inverted, perverted thing? Presumably, there is a way, from Eru's point of view, of applying an inverse to Ungoliant's Unlight.

Presumably, much as at The End of Time (Second Prophesy stuff) where all things 'lost to the end of time' are kept, stored, or wherever they 'go', as that applied to things of The Flame Imperishable, equally, unlight has some kind of role in any reformulation--in a repair or revision of Arda's fabric.

We will never know, I suppose, what the evolution of the mythology would have entailed.
