So the time it took Reach to fall in the game, compared to the book, is quite different, also there was an Easter egg in Reach that showed the Chief in cryo on the ship, but i think that conflicts with where he is supposed to be at that time. Also i don't think the PoA ever landed on Reach in the book. So i know retcons happened, all im asking is, what parts of the book "Fall of Reach" are still canon? For example, in the new canon, did the PoA still participate in the big space battle like it did in the old canon? Or did it just leave Reach and jump to Halo?
