The long period of time hanging in the sky as a surveillance satellite did not change the innate character of Gawain but brought him a distinct perspective on the universe —— when necessary, he could use the attitude of almost a complete bystander to analyze the transitions in this world and sum up some possible rules from the frequent changes that lasted thousands and tens of thousands of years. And these rules, to the species living on the ground (including those elves who had lifespans of a few thousand years), were difficult to summarize.
Precisely because he had witnessed the rise and fall of civilization multiple times, Gawain could speculate that the Dark Wave happened more than once —— even if he hadn't caught any one of those times, the surveillance images before and after the occurrences were enough for him to guess what had happened in between.
And in another of Gawain's guesses, he thought that the scale of the Dark Wave was uncertain.
