Now that the magic story has come out and we have gotten into spoiler season, I want to ask again how your Fan Plane would weather the Invasion of New Phyrexia?
Alright, in no particular order:
Ocaelum: Was deemed a worthless, dead plane by Gitaxian surveyors, since Realmbreaker emerged in the skies of various plane. As such, Ocaelum's inhabitants didn't even notice anything happen.
Moloni: The specifics of Moloni make defense of Sources orders of magnitude easier than attacking them, which worked out mostly good for the defense of the cities and castles... But not so great for the rest of the plane. Thankfully, the invasion was short enough that most of these bastions didn't run out of food or water or lose a siege, however, there might be upcoming issues from the logistic support of them taking such heavy hits. And maybe much worse if Realmbreaker dug deep enough into the ground to pierce the Nullstone layer and trigger another tectonic eruption.
Winrovah: Ah. Well, Winrovah didn't have much of a defense to put up in the first place, and Realmbreaker evolving in the Blind Eternities means it was protected from the effects of Aether and Void there. However, the same could not be said of Phyrexians it carried. Overall, a lot of death and devastation, and Winrovah didn't need that, particularly when things were looking not-as-grim for the first time in decades.
Geonne: Probably did the most averagely of all these, but it's mostly because I know the least about it. Probably more chimeras there than before, both compleated and not. The hybrids there leave room for a lot of peculiar compleations.
Ferely: Ferely had organized angels and really possessive archdemons that didn't want to lose their people to new masters. There were losses, but none of the archdemons fell or embraced compleation, so the worst was avoided. However, probably some compleated Saints and Apostates that created a bit of Havoc.
The Haven: Benefit of being aware of the threat well in advance, of having faced it before, and of having already prepared interplanar countermeasures in place. The actual structure of the Haven was mostly abandoned aside from one aisle before, but most of the population of the (small) plane was able to take refuge into it temporarily by occupying those parts of it. It held.
