An adventuring party recruited from Osirion teleports into Azir on the 8th of Desnus. Rahadoum's recruiting contact in Osirion wrote ahead to note they were expected. Couple of guys he's known a long time - a wizard, a ranger - and a new guy, sorcerer, probably to replace the cleric they usually travel with. They spend two days in Azir getting oriented and head out to the front. The ranger wears an unusually high quality amulet of Nondetection; the sorcerer wears a headband for intelligence, which is a bit unusual as sorcerers usually don't need it to cast, but some variants do; they are otherwise unremarkable. Chaotic Good, Lawful Neutral, no reading, which could mean neutral or 'hiding it'. They work quickly and effectively, manage resources reasonably well, get recommended to higher-ups for a closer look on that account.
Leareth is standing nearby - his head turns. :Nayoki, are you all right?:
Asmodeus gives a random priest who arrived to the temple too late to be caught in the enchantments twelve more cleric levels and a shove to his knees to pray -
And he distributes twelve more cleric levels too, in the same instant, he has bound himself to act just as much and not more and this may destroy the world but it is the best shape to be in expectation -
- Huh, something feels different, it's - like he has suddenly deeper reserves, except it's not his usual reserves, it's the other kind. The kind that comes from Abadar. It's not exactly twice as much as before but he has a sense it's the right amount to get him an additional level's worth of spells.
What is he even supposed to do about that - there aren't any clerics around he can ask, Rahadoum's army doesn't work with them, he's kind of a one-time exception here.
He didn't spend very long looking through the list of higher-level spells but he tries to remember, briefly, if any of them are useful enough to be worth stopping to ask for, rather than just going on with his normal, right now much stronger kind of magic.
All right it probably doesn't take that long to get one spell and he doesn't have anyone else to cast it on him right now - he's mostly not using magic, he's here to coordinate, but obviously more backup is better.
He Mindspeaks some mages to cover him, and also Mindspeaks Taver to let him know that he appears to have gotten more cleric powers and given how the gods work this probably means Asmodeus is up to something. And then he gets out his holy symbol and kneels and reaches for the now-familiar interface with Abadar.
He'll definitely take three of it! Leareth pushes a feeling of gratitude toward that now-familiar presence, which is still kind of terrifying but also its own flavour of reassuring.
Leareth relays to his mages, telling the nearby ones to swap to heat-sink shields; he's also not sure Velgarth magic is the best bet against this, can Taver ask some of Aroden's wizards for advice.
It does something! Much less than it'd do to a person, but not nothing.
The devil takes off in the air, flying towards the army.
Some more devils join it.
The trembling cleric of Asmodeus stands up from praying for spells and asks Asmodeous to miraculously fix everyone in the temple who has been affected in some way by the invaders. Whatever it is that the invaders did.
They can throw lightning bolts at each other.
High Priestess Aspexia Rugatonn gets herself miraculously cured, scrambles to her feet, gives hurried orders to make sure the fight for the city is as costly as possible for the attackers, Plane Shifts to Hell.
Not to that deepest level of Hell where Asmodeus is, of course, you can't get there with a Plane Shift and would be very unwise to go uninvited at all. But in the first level, Avernus, they'll at least be able to plan their response unimpeded, and their enemies seem quite competent to impede them in Cheliax itself, right now, somehow - how -
It is a question than an extraordinary number of devils and demigods in Hell have already been set to answering. They watch backwards in time through the last hours, weeks, months, years, they learn of another world and send their searching there, too -
- they are interrupted by an invasion of Hell from Heaven, because of course they are -
Leareth Mindspeaks Taver for an update on how the city is responding - the defending soldiers and clerics, but especially the local civilian populace.
In addition to being able to Broadsend to thousands of people at once, Taver is an incredibly powerful Thoughtsenser, and most of the citizens don't have much in the way of shielding. He has to stop Mindspeaking to do it, but everyone's heard the message repeated quite a few times now, and he can divide his attention to reach across miles, skim a hundred people at once and then another hundred, consolidate an overall impression - how are people reacting?
People are so incredibly terrified! They're terrified that this is a ploy of some kind to test their loyalty. They're terrified that it's a war between gods and they're all going to die. They're terrified that they're going to be killed for picking the wrong side, or for not picking a side fast enough.
(They're hopeful - but it can't be true, and someone'll ask them, next week, maybe under a truth spell, did you desert your loyalties so easily, are you so worthless to Asmodeus, is there nothing of you that will remain when the unworthy bits have burned away -)
They cower in their homes and remind themselves that someday Asmodeus will conquer all the worlds, that people believe going to one of the nice afterlives is an escape but Asmodeus will come for them there, too, that hope has always been the enemy of good judgment. Some of them are thinking about which neighbors to accuse of disloyalty when Asmodeus wins, and as a backup plan which neighbors to accuse of disloyalty to the new regime if Asmodeus somehow loses.
Being upset about it right now won't help, so Leareth isn't, he folds that away for later. People cowering their homes is one of the best options, here - in some ways better than them joining the fight on Aroden's side, because that risks a lot of untrained civilians getting killed in crossfire.
He asks Taver to switch his focus to the soldiers and lower-level casters, who won't be the focus of as much attention, and to start divvying them up into sections based on who is near which of Leareth's mages, and inform said mages that a particular contingency-order is now in effect and of who their assigned people are. Oh, and also to let Aroden know he's doing so, so things don't get tangled up.
In between throwing attacks and shielding themselves, Leareth's mages find moments to reach out with compulsions - for those who don't have Thoughtsensing, Taver can help them anchor on the right minds. Casters first, then common soldiers.
The compulsions that go out are subtle. They'll show up to enchantment sight still but hopefully most people are too busy to check. The soldiers and casters affected are just going to be missing and fumbling a lot more attacks than they would otherwise.
Cheliax starts sending in forces from elsewhere in the country, only the ones that can Teleport for now. Asmodeus is being extremely generous in granting prayed-for Miracles and in sending more powerful and more cooperative devils than you'd ordinarily get from these planar binding rituals but not, so far, intervening farther than that.
They need people who can do Gates. The obvious thing is to try to grab some, with Dominate Person or Geas spells - convince them to switch sides and be rewarded in this world and the next one -
Leareth and Aroden were expecting this, because it's kind of the obvious next step for Asmodeus. They tested the spells against Velgarth shielding, which can shield out any mage-compulsion, but apparently that's not the case here; it makes it more likely someone can throw off the spell, but doesn't render them immune.
With more lead time they could have figured out shielding, either a local magic item or purpose-built Velgarth spell, but as it is, the best he could manage was a voluntary compulsion on all his mages. They know what Dominate Person and Geas feel like; some had it cast directly on them as a test, others with Mindspeech rode along in their minds or observed the memory. The compulsion is a subtle, conditional one; all it says is that if they sense enemy mind control, they must immediately stop taking actions, and contact Leareth and Taver, either with Mindspeech or a communication spell or a one-time-use emergency talisman for those who can't manage either.
How Leareth will respond to that is going to depend on the exact conditions, but having Taver to coordinate through gives them a lot of better options than they would otherwise have.
