All the exultation is quenched in an instant by icy water in her veins.
She doesn't get to keep the Crown of the Most High.
And even if she did, if Fox's Cunning plus Owl's Wisdom does to Keltham, anything like what it does to her -
They could lose at any time. Any instant. They can't have a plausible story ready to give Keltham when he asks for a Fox's Cunning, because Keltham is always walking around carrying the Conspiracy inside his head, and a plausible story is going to sound exactly like what the Conspiracy wants him to believe. They need to show him something that convinces him he doesn't want a Fox's Cunning, beforehand, and he will know that it's something that the Conspiracy would want him to believe.
But they have one advantage. They have an advantage, if Keltham is giving them an accurate picture of how he's thought so far, Keltham might credit, maybe, that in the Conspiracy world, Cheliax would never be crazy enough to tell him that Fox's Cunning or Intelligence headbands even existed. Which, to be clear, they absolutely should not have.
And - if they lean on that, here, Keltham then learns a further true fact about the Conspiracy, in the world where the Conspiracy is real. He learns that they are learning as they go, that they were stupid enough at the start to tell him about Fox's Cunning but then changed their minds later; in the world where the Conspiracy existed, that will obviously be what happened inside the Conspiracy, even if it seems improbable and shifts belief in the Conspiracy downward for that moment. He'll think the Conspiracy is less probable, for the moment, but inside that hypothesis, knowing that takes him closer to the real Cheliax, closer to the truth about Asmodia playing the game against him.
It's still a forced move in the game. If Keltham gets a simultaneous Fox's Cunning and Owl's Wisdom, Cheliax loses. It's probably that simple. Why hasn't he asked for that already?
"Yeah," Asmodia says out loud. "Why don't you stick around, Ione. Security, I need Sevar in this room, or if she can't be here then I need messages passed fast enough for two-way conversation."
