Specifically, Razmir, fully buffed and with is backup suite of magic items accumulated, has used His messengers to inform His forces that He will descend to punish the undead and Chelish scum who dared to assail His fortress, and show them the wrath of the Living God.

He is short most of his Pearls of Power, since they were in an extradimensional space on his corpse, but he didn't spend his Teleports and he can scrape together an amulet that can Plane Shift him to Thronestep so as to coordinate the destruction of these invasion forces. He informs them that he will be arriving in the Teleport Trap room shortly.

Oh good!

(Telri's been in the teleport trap room in Thronestep since the crisis broke out, mostly doing healing and buffing for the troops garrisoning Razmir's capital as soldiers are rushed hither and yon from crisis to crisis.)

He's out of Rods of Quicken Spell, so he uses the Plane Shift down to Golarion, and then he can Teleport over to Thronestep -

No, actually, he cannot. Her daughters have been scrying their wayward sister since the day began, and Razmir cannot be permitted to continue existing. Carnaneth releases her readied Greater Scry as soon as the word is given that Razmir is on his way, Arcanist Fainalach casts the Greater Teleport, Carnaneth's daughter Guecoth casts the Antimagic Field, and Thossbraigh and Carnaneth herself beat Razmir unconscious. Once they've stripped him of his magic items, Guecoth has released the spell, and the wizards have shattered his defenses, Fainalach readies the gem, Thossbraigh cuts Razmir's throat so he starts bleeding out, and the Arcanist casts Trap the Soul.

There will not, actually, be any resurrections, this time.

And then they teleport back to the most secure fortress of the Winter Council, hide the gem behind a vast collection of magical wards, and Carnaneth writes a very polite note to Cyprian-or-Cheliax-fill-in-the-blank to be delivered the next time they're thinking seriously about invading Kyonin, which says "tell me, which of us do you think Razmir hates more?"

Why would he invade Kyonin when Razmiran is right there, leaderless, and without the ninth-circle wizard who was the main reason it isn't part of his empire already?

He already has troops stationed on the border. They invade as soon as he gets enough confirmation via scries to be reasonably sure that Razmir is off the board, and Razmiran begins to collapse at approximately the speed a Galtan army can walk.

Lastwall has spent most of the past night doing things unrelated to Razmiran, such as 'rolling up most of their spy operation in Cheliax', but they do, at some point, piece together most of what happened, and contact the surviving Twin, offering to negotiate a price for access to Razmir's demiplane and any of his magic items that Cheliax didn't get.

Erna indignantly rejects Lastwall's insulting offer, on the grounds, first, that she leveled, second, that the Living God is not dead, third, that the morning after the attack when everyone got their rest, she prepared spells and started to hunt out all the vampires she could find (and failed to find any because they sensibly left, having won), and, fourth, that she is therefore ruling a large and powerful city which, since she is Razmir's most powerful priest and everywhere else in Razmiran is being rolled over by Galt, is the natural hub for fleeing Razmirani loyal to the Living God to gather, and she therefore has a quite considerable army by the standards of city-states if not by the standards of the Great Powers. If anyone is going to bear the mantle of Regent of the Living God, it's her.

(In practice, nobody is; the Freak Out Completely switch, once flipped, will stay flipped until Razmir un-flips it, which does not look like it is going to happen any time soon.)

She is, of course, opposed by the new king of Ustalav, not that there is anything the King of Ustalav down south of the Hungry Mountains can do about this, or indeed about anything north of the Hungry Mountains.

(New king? Oh, yes; Carmilla has a nephew of the royal line. Dutiful young man, listens to his aunt. Absolutely the King of Ustalav, and there is nothing Lastwall can object to in a Lawful Neutral king, that they might find reason to complain about in the Neutral Evil Queen of Caliphas, or, worse, the red-eyed gentlemen who she occasionally consults for...)

At any rate. Ustalav has a new king, and if his writ ends at the Hungry Mountains to the north and the Destach River to the east, that's at least better than the last king, who did not, in practice, have a writ.

The oath does, of course, restrain the undead... somewhat. It does not take them long to find loopholes, have subordinates provide them with convincing evidence their allies have violated it that they choose to believe, or, in some cases, die and return to life with all permanent spells stripped from them, their acts of outright war against Lastwall and the Palatinates under its protection being comparatively limited. Still, the Whispering Way does not... quite... disintegrate into civil war, and it does do its best to slaughter any paladins that come into Ustalav, its best being pretty good...

... And it does have all of Amaans, Odranto, Sinaria and Barstoi - the northern half of Ustalav - as a completely free and open ground for reestablishing "the Whispering Tyrant's" rule in the North, from which it can fulfill its oath. So it certainly considers things to be looking pretty good for the cause of Undeath.

Tell me, lich, do you know what it is to have the very fires of magic that maintain you crumble apart, to be wrenched limb from shuddering limb as your eternity streams away into the maw of the ever-hungry void that is my sole true patron?

Your vampiric comrades know.

Sinaria is MINE. And the Sons of Flame will guard it. Depart, and you may keep your petty eternities.

(And she can go back to her pre-Razmir life of running an independent slaver state. Ah, life is good.)

I have no objection to anything that has happened aside from Razmir disappearing from the map before he could give me more magical advice. These are the borders of Varno, they will be irregularly enforced by very high level vampires eating you, that is all goodbye.

Razmir's loyalists may rule the city of Kavapesta, but the hills of western Amaans they have left alone, and those are within reach of Lastwall's patrols in Virlych. It will strain their resources to actually patrol Amaans as well, and they will let nothing distract them from their sacred charge to guard Tar-Baphon's prison, but they owe it to the people of this county to do something.

Lucinean Galdana survived the night of blood, fleeing his fortress and hunting vampires from the shadows of the woods, and the compulsions on him were broken when their caster died in the defense of Kavapesta. Supported by the force of Lastwall's arms and the love of his people, he once more becomes takes up his bow, and with it the mantle of the wandering Count of Amaans, making what headquarters he has in the town of Eran's Rest.

Iomedae's church will, of course, gladly supplement the now-shrunken Church of Pharasma in the county. The two churches are not entirely friendly, but the rivalry never escalates beyond occasional heated sermons, and they share a common enemy in the county's still-substantial undead population.

The Count of Barstoi is dead, leaving no heir, and among his last acts was to beg Cheliax's assistance. The vampires that killed him have vanished, but there is still an undead menace in the area, which will certainly take over if someone else doesn't.

These sound like perfectly Lawful grounds for an intervention.

They send another several dozen Hellknights of the Order of the Scourge, which once assisted Count Neska in the rule of his county, accompanied by lower-level troops and a support staff of wizards, to rule the county in Hell's name and as Cheliax's protectorate. (There are, however, no clerics of Asmodeus among them, and no overt attempt to establish the Asmodean faith. Yet.)

They are happy to assist in the defense and maintenance of the road to the Worldwound, which runs through what is now their territory, for an appropriate fee.

They weren't in fact going to be able to defend the road themselves, with the rest of Ustalav in the state it's currently in, but, ugh.

Ah, snacks.

And Northern Ustalav continues its slide into absolute and total warlordism, and the complete collapse of any and all Law and Order.

And the great nested demiplanes of Razmir, in which the finest wizard of an age hid a vast collection of magical items of unmatched potency guarded by legions of powerful constructs and summoned beings, including (if rumor holds) a pair of enchanted gloves bearing the powers of every metamagic rod known to man, become the subject of rumor and legend among high-level adventurers, some of whom attempt to seek out the Three Keys that access his hidden realm, causing various minor amounts of trouble for Cheliax and Galt along the way.

You know. Adventurers.

Of course, when, several years later, a mixed-alignment adventuring party gathers in a Lastwall tavern, that isn't quite the prize they're talking about.

"- So I can get us in, but I think you're overestimating how much good that'll do -"

"- Just polymorph us into elves, right?" the man in the tiger-helm says. 

"Bit trickier than that," says the (junior) paladin.

"Right. 'All elves know all other elves' is an overstatement, but they'll still go 'hey, someone I don't know in a secure place, how odd.' Especially my mother's friends, they're paranoid."

"And there will be demons to kill, of course."
