So what options for survival are left? a) Space - they would have to find a spaceship with fuel somewhere. Not very good plot, but possible. They would also have to find food and water for crew for long enough time (5 years?). b) They find a shelter on Earth. The problem of food and water remains same. Only possibility is shelter for few, rest in some form of cryo sleep c) They find 4% of surface not hit by radiation and live from it. Problem: how do you transport several thousand people there?
None of these options is good. Nightblood will not save them - the problem with food and water remains. So - what are your ideas?
All of them. There is no good solution. Every plan is bad. They’re going to have to cobble a solution together using bits and pieces of every solution to make it work.
They’re still dropping hints about what solution might be out there. None of it has come clear yet. We still haven’t found what we need to find, but they’re leading us there, so I’m sure we’ll be discovering more. It seems as if the first apocalypse is a lot more linked to the second apocalypse than anyone first realized. The stories are coming together. They’re going to need the the solutions from the first time to get them through this one.
