Thank you for all your comments.
Right now this is what I see happening as far as the series goes:
AA V - They get to the promised land. I will wrap up the loose ends to date and probably add some. The problem is, at least in my life, is some loose ends never get tied up. Shit just happens. Also it is too much to expect that a group like this would see more than a leg or two of the elephant. Should something like this ever happen I think that is going to be very true. Especially with the Internet down, and if it is working, like we have seen in Egypt, severely crippled. It's going to be word of mouth and whatever passes the ruling party censors.
In AA IV I was going to write the start of the next leg down. I don't think there will be a quick descent to a state of total savagery. There will be a bottom at a level of technology that will provide the support for a new civilization. I have not figured out what that level will be, I am still thinking 1880's. That period, if you were born then, went from horses and trains to cars, rockets, and TV in your lifetime.
Then I hope to write more Gardener books. Right now I am thinking once he gets to the promised land and the Horde settles in he gets bored and goes off to rid the area around it off bad people. This just struck me -- perhaps as Freya's Marshall.
AA VI - will be the final, or as final as life gets, battles.
As far as characters go I consider some of them the core to the story. If I kill them off then there is no more story.
