A few months ago, someone here started a thread revealing the original untold version of the show, in which there was the 5 year spin-off which actually resolved the story, where at the end of the first five seasons the Shadows destroy B5 and take out the Vorlons. I don't know the link or thread title. It might have been information gleaned from those script books you have pay $100 each for.
There was a complete set of all of the B5 books published on Ebay a few days ago for only a few dollars more than the regular price. Yeah, there are some individual copies listed for a hundred bucks apiece but they're not selling, either.
Yes, there was an outline in Volume 15 (the bonus volume) that was written by JMS very early in the first season. But B5 was *not* destroyed by the Shadows. From that timeline:
If the other thread indicated otherwise (and I don't think it did), it was in error.Season Five ends with an assault on, and the destruction ofBabylon 5 by the Minbari.
