As a narrative experiment how would one handle a dual timeline campaign where it's the "same" characters in both timelines, that are roughly 20 years apart. In the earlier timeline they start as 1st level characters, and in the later timeline they're 10th level or higher. It's the same characters and there's a bunch of ambiguous details of events over 20 years that get filled out as things happen, some things from the past timeline can certainly effect things in the later timeline.
I feel the later timeline for example needs to be more narrowly focused, as something that happened in the past one will become "Remember that time we did this?" in the future timeline, and things mentioned in the later timeline might steer the direction of things in the past timeline. And then there's the question of what happens if or should a PC die in the past timeline, which might need some narrative work to explain why someone like them is still around in the future.
