shit is already pretty grim in westeros. king's landing is falling into chaos. the royal lines are being killed off. starks are mostly destroyed, lannisters are broke and their line is destroyed, same with barratheons, tullys, no more targaryans. the small folk are about to be royally fucked by winter because their harvests have been destroyed by war. then you have the WW getting ready to kick the shit out of everyone who isnt already dead.
yeah, things cant be much grimmer there. what would an azor ahai do? kill the WW? restore the realm to one true king? none of that will change the damage thats already occurred and the starvation setting in for winter.
