Alter Self back to her usual human form?

Nope.

That's suggestive of them being under Baleful Polymorph. Aspexia said not to bother, but—not being able to Alter Self is going to be annoying. Dispel dispel dispel?

Nope.

... Alter Self to a different pony form? (She chooses Aspexia's; it's easier to target a form you've actually seen and she's sure as Hell* not turning into the horrible pink thing.)

(*A more literal expression in Cheliax than in most places.)

Works!

"Huh. Assuming you just did what I think you did, that's...outside the range of things I was expecting. I suppose that magic is known to work differently on different planets, and if the dominant species on this planet have this form instead of being humanoid—it's plausible that Alter Self would work that way."

It is suggestive of them being really, really fucking far from home, though. Perhaps even that the Iomedaens just destroyed their souls like sensible people and now they're being simulated by an alien power outside Creation altogether. She's going to mentally live in the world where that isn't true, for now, not because she's unwilling to face it but because if it is, there aren't any useful actions she can take anyway.

"Another planet as in not a Good afterlife?" That would be great.

"I know what you're thinking. No."

"You can't, actually, give me orders. Besides, I'm sure there'll be room for Asmodeus' church in my new pony empire."

"Until such time as our Lord has bestowed the rule of Infernal Cheliax on another Thrune, which did not seem likely to happen anytime soon last I checked, you are bound by contract to give your life, if necessary, to ensure that it remains an Asmodean state."

"As far as anyone on Golarion is concerned, I did. What's the difference between one Asmodean state and another, anyway?"

"We were ordered to establish another Asmodean state on Golarion, and the way of Asmodeus is to obey, not to do what you like and then convince yourself that it benefits Him."

(This order is news to her.)

But of course. Golarion is Rovagug's prison; this is what the literal name of the planet means in Infernal. It's also where prophecy is broken. And Asmodeus holds the key to Rovagug's prison, a fact which, while undoubtedly not literal, still has to be true somehow.

Perhaps Asmodeus fought for Cheliax like the fate of the world depended on it because it did.

...no, that can't be right. Iomedae and her puppets wouldn't have been allowed to prosecute the war if it had risked Rovagug's release. But maybe, if Asmodeus can't maintain the security of Rovagug's prison, the key reverts to Someone else. Or something like that.

Abrogail doesn't say anything, but Aspexia is very good at reading facial expressions. Shit. Now is not the time for Abrogail's loyalty to be in doubt. Under the circumstances, she wouldn't normally even care, except that she doesn't have spells, and Abrogail still does.

"I will consider your duty discharged if you can get me back to a place where Asmodeus can give me spells," she says. "As for what Asmodeus Himself considers to be your duty, I suppose you will find out eventually. He does still own your soul. Personally." Even if he loses all the rest of Hell.

(Although the same ought to be true of her, and she still isn't sure that Mephistopheles hasn't somehow ended up with them both. Perhaps He and Asmodeus made a trade—their souls for more of what Asmodeus valued in the new Hell, or something like that. In that case she shouldn't try to oppose Mephistopheles' hypothetical aims, lest she retroactively make the bargain more expensive for her Lord—)

Hmm.

Flesh to Stone.

No one on Golarion would have had much of a chance of landing that spell on her in combat; otherwise, she would have been a statue a long time ago.

Of course, she isn't in combat. She's unbuffed and itemless, and though she's also younger, in this form, it isn't enough. Her flesh is stone.

She might regret that. But Aspexia was looking pretty likely to just be a damper on her—activities. (She's careful not to even think the word 'fun', lest she re-summon the pink fun demon.) And Asmodeus—well, she's near-certainly outlived her usefulness to Him. If He'd like to spend the resources on tracking her down just to torture her, He can—but He seems to have more important things to worry about.

She walks off in a direction that looks like it might lead to civilization.

Eventually Abrogail will encounter a pastel yellow winged pony singing to herself as she picks flowers and puts them in a basket on her back.

"Eep!" she cries when she sees Abrogail, immediately ducking behind a large basket of apples.

What fresh torment have the gods of Chaos prepared for her now?

"Hello?" she says, in a voice that would sound downright timid to all but a few people on Golarion.

"Hello," replies the yellow pegasus, peeking out from behind the apple basket. "I'm sorry, you scared me."

"Do you know which way the nearest town is?" she asks.

"Oh no," she says. "Are you lost? Maybe my friends and I could help you get home."

"I doubt that," she says. "I just want to know more about where I am."
