He doesn't last long in a torture chamber before he starts promising to give up all the details on Andoran's secret operations demiplane as long as they swear not to torture or Maledict anyone there.

(They switch out demiplanes every few weeks anyway. It isn't too great a cost.)

They'll take that deal.

Riudaure gets a Sending: "Extraction imminent. Team briefed on Augustana plan, proceed if possible. Acknowledge only if safe."

He doesn't say anything. It's not safe.

A Gate opens, and the Grand High Priestess of Asmodeus steps through, flanked by several lesser Asmodean clerics and followed by two dozen elite Chelish fighters.

"This demiplane is mine," she says. "Are we all in agreement or do we need to have a fight about it?"

SHIT.

Even priestesses of the Chaotic Good goddess of revolution recognize that the rules of combat in Golarion are that the ninth-circle caster wins.

That said, they do have a plan for something like this. She starts joining hands with the other Andorens, plus Riudaure, preparing to Plane Shift them to Elysium.

Dimensional Lock.

"That," says Aspexia Rugatonn, "was as predictable as it was foolish."

She looks at Riudaure. "Did you get a good look at the gatehouse."

"Yes, Most High," he says, kneeling.

"Take my hand."

He rises, and does so, mostly not terrified.

"Kill them all," she tells her subordinates, and Plane Shifts both of them to the Material.

Clerics, even ninth-circle ones, can't teleport within a plane. He has to do it, and while Rugatonn could easily resist an involuntary Teleport, she doesn't get any information about the destination before making that decision.

The Grand High Priestess of Asmodeus is, in this moment, completely within his power.

He's only ever seen the House of Oblivion in a scry, but it's within his Teleport range. Even a ninth-circle cleric probably can't walk away from landing on its doorstep.

He knows the odds. It's only three in four that they even get close enough that Rugatonn has a chance of losing. It's probably more likely than not, in the end, that she walks away and he suffers in Hell forever.

(He starts weaving the spell.)

There are people who would make that trade, but not him. He doesn't, actually, want to die, even to Abaddon rather than Hell.

They land just outside the Forbiddance of the gatehouse of Augustana.

Dispel Magic.

The Forbiddance shatters, and a round later there are a dozen simultaneous Teleports and the gatehouse is basically taken before the fight even begins. Riudaure doesn't even really get a chance to join in.

An eighth-circle wizard, one of less than ten Teleporters whom Aspexia actually trusts not to send her to the House of Oblivion or the heart of the Worldwound or anywhere similarly stupid, Teleports her away to safety, and then they raise the gates. The battle for the city itself, such as it is, doesn't last long either.

Riudaure, somewhat predictably, is arrested while they investigate the whole "fake defection" business.

He suspected it was going to go like this, despite the fact that he just delivered them a city of vital strategic importance and somehow, also, Andoran's secret operations demiplane where they keep their wizard prisoners. Well, mostly Aspexia Rugatonn did that, but she evidently wouldn't have bothered if he hadn't come up with the plan.

—how did they find him? He wasn't thinking about that in the heat of combat, but it's hard not to think about now, chained to the wall in a torture chamber back in Egorian to await his fate. The probability that they chanced upon the intelligence somewhere else at precisely the right time is obviously quite low. Andoran must have given it up on purpose.

This is a trap.

He doesn't tell anyone, because he doesn't actually want Cheliax to win.

The interrogator comes in. She's a woman, which isn't unusual, though she's young for her apparent rank, and rather prettier than one normally sees in the army. Her clothing is plainly expensive, plainly intended for combat, and very Asmodean in style, but is not actually a Chelish military uniform. That's somewhat more unusual.

She casts Mind Probe. There's something strange about the way she casts the spell, though Riudaure lacks the context to identify it.

(There are few people in Cheliax with the Sense Motive to reliably beat Riudaure's spectacularly high Bluff, but there are any.)

"Did you, in the course of this operation, knowingly betray Cheliax?" she asks, the force of the question carving into his mind in search of its answer like a knife.

"No." Well, only as a deception.

"Do you expect any harm to come to come to Cheliax as a result of your actions, intentional or unintentional?"

"I'm not sure how you found me. It seems likely that they leaked that information and therefore that this is some kind of a trap." No point trying to hide that at this point.

"That's a wise thought," she says. "Security." She gestures at presumably an invisible wizard in the corner of the room.

Break Enchantment.

Remove Curse.

He's not enchanted or cursed, so this does nothing.

"Are you loyal to Cheliax?"

"I'm Evil. I'm loyal to myself. Keep my incentives aligned and I'll serve you well."
