terraforming or something else?

As far as I understand it, the oxygen given off by trees might aid in the formation of rain and in the formation of an atmosphere, right? Here is something interesting - remember that Lune is bigger than the moon in our time, according to Rudesind the currator. This either means it was moved closer or it was replaced with a much larger object. When the long night begins in the miracle of Apu Punchau, instead of the ship blocking out the sun, could Severian summon Urth (a doubled version he grabs from somewhen, maybe when he feels himself doubling and splitting in two in that scene where he leaves through his own ear in Citadel of the Autarch at the pelerines altar) and replace the moon with it? Could the passage of the white fountain create a twin of Urth? To save Severian in the past with an Urthly eclipse? Could reality have been altered in the solar system so that there are, and always have been, twin worlds? Could the introduction or swapping of a planet produce an unstable orbital pattern such as those exhibited by the blue/green system? Could the picture of buzz aldron just be from a previous cycle? I am sure that Green is Urth now. But I don't know what blue is anymore. And if Mr. Wolfe randomly doubled the Urth system, how the hell were we supposed to figure that out? Seems like cheating either way, doesn't it? By the way, there is evidence that there isn't the same kind of biotic life on Blue that there is on Green, and that Blue is even colder than the Urth of Severian's time. Here is my question - if Green is bigger, but farther away, than the moon of our time, what kind of effect would it have on the tides of a hypothetically flooded moon? They would be greater from farther away than the effect of the moon on our tides from a closer range, right? And if people were doubled somehow, and the planet doubled as well through some kind of mirror reality created through Inire's mirror universe, might not they appear doubled in limbs, too? As the vanished people do? Have people gone up one dimension, and as a result become "weird" looking? I am so confused right now. Marc Aramini

Maybe I'm just stating the obvious here, but the "doubled" people seem right out of Aristophanes speech in the Symposium. See: http://ibiblio.org/gutenberg/etext99/sympo10.txt. The Neighbors are then the "old guard" - they're the best the classical world could come up with, yet have failed to meet the challenge of the inhumi. It's time now for Christianity to have a go at it. Where do the Neighbors go? Into mythology.
