Indeed - that's why I'm using Wavecatcher's installments as reference, since somehow the "eight-and-four floodings" since he met Yun seem more feasible than the 200 years post-Shards.
I'm assuming with "flooding" he means something akin to a monsoon (it's a jungle we're speaking of, after all)... I wonder how often would those occur on Abode? My guess is two or three times a year as this would set the events of "WaveDancers", ipotetically, four years after Shards - if I did the math right, about the same time Chitter was born? Then there would be three years between the not-existant end of "WaveDancers" and the beginning of "Discovery".
