"Yes, it is."

Disintegrate.

Not even a ninth-circle cleric has much chance of making her save against a Disintegrate prepared in an eighth-circle slot by a wizard with a Greater Rod of Persistent Spell and as much Intelligence enhancement as magic can achieve. She goes down.

And Felandriel Morgethai activates the device she's carrying, a simple combination of a tiny Bag of Holding and Portable Hole, which when combined suck everything within ten feet—namely, herself and the ashes of Aspexia's corpse—into the Astral Plane, Forbiddances be damned.

(Bags of Holding still work fine in a Forbiddance, even though they're obviously interacting with other planes, so clearly when the gods designed Forbiddance they carved out a special exception for them.)

And from there she can Plane Shift back to the Material, leaving Aspexia's ashes to drift and scatter.

And then she immediately removes her ring of Malediction, commissioned at great price from a Kuthite cleric who also dabbled in magic items, which has the effect of temporarily actually changing one's alignment to Lawful Evil—strongly enough to fool Forbiddances, but also strongly enough that, had she died while wearing it, she would have actually gone to Hell.

She's hard to kill, especially quickly, but it's still a risky item to use.

She Teleports back to Egorian, to the edge of the palace Forbiddance, now wearing her true form.

Go in one round, she says into her Telepathic Bond, and then casts Mage's Disjunction, as ought to be sufficient to break even Aspexia Rugatonn's Forbiddances.

It breaks.

All of the Security have responded to the incident in the ballroom, for all the good it'll do them now, but there's one seventh-circle Asmodean cleric sprinting for the edge of the Forbiddance, trying to get news of the attack to Hell before the situation gets even worse.

"STOP."

He was going to stop anyway, what with fucking Felandriel Morgethai being right there, but okay.

Well, he did reach the edge of the Forbiddance, in a manner of speaking, but now his tuning forks don't work and he also cannot take any actions.

She casts a Touch of Idiocy, to further wreck his Will save beyond even what disabling his headband already did, uses her Pearl of Power, and then, using her Rod of Quickening, casts two Teleports in the same round, to the House of Oblivion and back, leaving the still-stunned, stupid, and forkless cleric to be eaten by divs. She's not as bothered by sending Asmodean clerics to Hell as Iomedae's people—they, perhaps alone in Cheliax, did choose it—but they need as many of Cheliax's high-level clerics as possible to be un-Resurrectable anyway.

(At INT 28, with literal centuries of combat experience, one can just come up with plans like this without having to particularly take time to think about it.)

And then basically every person allied with Andoran who can cast Teleport appears in the Palace's inner courtyard, clerics and fighters and weaker wizards in tow, except for those who can cast Greater Teleport, who are in the ballroom already.

Abrogail is already gone. Within seconds of Aspexia's death she was Mind Blanked and being rushed out via one of the Palace's many secret escape routes, Security coating her in every protection spell her Crown didn't already provide as they walked, and the moment the Forbiddance fell they were Greater Teleported to an unscryable underground bunker in an undisclosed location far outside Cheliax. Even she doesn't know where they are now; it's safer that way. She demands to watch events unfold via a scry; as long as Morgethai took out all of the Palace's scrying protections they might as well take advantage of that.

Meanwhile, a few blocks from the Palace, in the High Temple of Asmodeus, an apparently unmagical man knelt in apparent prayer pulls a scroll from inside his cloak, reads it off, and Disjoins that Forbiddance too.

As in Augustana, the people who Teleport in are mostly not, formally speaking, Andoren forces. Those have mostly been reserved for the main assault on the Palace. It turns out, however, that an opportunity to loot the High Temple of Asmodeus for its impressive collection of divine scrolls while Cheliax is extremely distracted attracts rather a lot of adventurers, even recruiting only Lawful Good parties under conditions of strict secrecy.

The temple is nearly deserted, compared with its usual state, and those clerics who are about are generally of lower level. All the important people are at the coronation. It isn't a long fight. Nor is the vault where the scrolls are kept particularly hard to get to; it would be, under normal circumstances, but normal circumstances include "being under a Forbiddance" and "not having had all its magical protections Disjoined". It's a simple matter, then, to Dimension Door in, fill one's Bag(s) of Holding with scrolls, and Teleport out.

Across Cheliax, similar assaults on lesser temples are triggered at the same time. Most don't require ninth-circle scrolls; all temples where scrolls are kept are Forbiddanced, but generally not by Aspexia Rugatonn herself.

The adventurers' contract requires them to turn over scrolls of Resurrection, True Resurrection, or Miracle to the Andoren government; all others are theirs to keep.

Back at the Palace, some people may not have realized there was going to be a pit fiend in this fight before they started it.

They realize it now.

Within two rounds of the Andoren forces starting to appear in the courtyard, he calls a Meteor Swarm down on them.

People who don't put Protection from Energy (Fire) up before going into battle don't generally live long enough to learn to Teleport.

That said, many of them now don't have it anymore.

And in a bunker far away, Abrogail watches the fight in the ballroom over a scry, and tries to figure out exactly what Andoran is doing. The high-level casters they teleported directly in (presumably with Greater Teleports; there's no way that many people got Teleport locations inside the Palace) are outnumbered by the Security that were already in the room, but they're not really fighting like they're desperately outnumbered. They actually barely seem to be casting offensive spells at all?

Meanwhile, the larger but lower-level group outside has a pit fiend between them and the fight, and additional Chelish casters are being Teleported in as rapidly as they can be interrupted—though mostly lower-level ones. The coronation ball was already using up most of Cheliax's supply of high-level Security wizards. They've resorted to pulling in clerics from the major temples across Cheliax—

And then she sees it. She's three standard deviations smarter than she was this morning, and it takes longer than that to learn to use that kind of an Intelligence boost for anything but spellcasting (in the case of wizards, which she isn't anyway), but she is learning.

The offensive spells they have been casting have all been almost exclusively aimed at clerics of Asmodeus, and they're strongly favoring spells that destroy the target's body—or Flesh to Stone, which keeps them un-Resurrectable in a different way. They're trying to take out Cheliax's entire capacity for Resurrection.

She conveys this observation to her Security who has a Telepathic Bond with Egorian, along with an order to fall back to the ballroom if it isn't obvious.

The order is passed along, and then word comes back along the relay that all of the now-unguarded temples are being hit for all their scrolls by what appear to be random adventurers but are, given the circumstances, almost certainly in the employ of Andoran.

"Order to Gorthoklek: end this now."

(It doesn't bode well for the future of her reign that her personal pit fiend was forced to use his once-yearly Wish on the first official day of it, but so be it.)

She gives her Security a round to convey the order, and then lights him on fire over the objections of her newly elevated Wisdom.

And then every non-Evil creature within four hundred feet of Gorthoklek is dead.

It's over.

...well, not quite.

It is not actually possible to design spells that do infinite damage to an arbitrary number of creatures with no save, which is what "kill every non-Evil creature within 400 feet of me" would try to come out as, naïvely. This is a mistake often made by Wishers who are new to having ninth-circle spells, though generally only once.

Gorthoklek is much, much Wiser than the typical adventurer who finds a Wish scroll in a dungeon or makes an ill-advised trip to the City of Brass, and also his Wish observably worked, so presumably it specified finite limits. The energy budget available to a ninth-circle spell using a diamond that large (or whatever pit fiends do, which is actually slightly different) allows those specifications to be very, very high, but Felandriel Morgethai's saves and also sheer number of hit points are also very high, and she had essentially every protective effect known to Golarion upon herself, either as a spell or an item, and she is, if barely so, alive.

Well.

He has Stun at will. Good luck doing anything with your remaining two rounds or so of life.

(He regrets only that his Lord didn't give him Malediction at will, but that's generally reserved for the devils who guard Avernus, so as to discourage Good clerics from trying to Plane Shift damned petitioners to Nirvana. Though sometimes they do it anyway.)

And she has one use left on her rod of Greater Quicken Spell, and one remaining ninth-circle spell.

Time Stop.

She's out of Teleports again after the House of Oblivion trick, but a ninth-circle wizard doesn't carry just one Pearl of Power.

She refills a slot, and casts Teleport, and collapses in a heap in the middle of the Temple of Sarenrae in Almas, where she lays until the Time Stop expires, and then a round more before she's blasted with so much positive energy and is approximately fine again.
