I call it “rolling canon” and here’s how it works:The current vogue is to imagine stories as taking place in discrete dimensions, like a railway with many tracks, some of which split, and some of which never meet.Rolling canon instead imagines stories as taking place in a contiguous fabric of realities that blend into each other like the colors of a rainbow. Not all realities are equidistant , but neither are they separated by a countable number of discrete intermediate realities.2/
