"Makes sense. They weren't spellcraft ideas, I do realize you'd be an idiot to trust me about that."
And she takes out a piece of paper and begins scribbling furiously.
One place Keltham might be safe outside the interdiction is the Worldwound, if he'd taken the oath, and he could talk to all of the allied churches there. Rejected b/c if anyone did want Keltham badly enough to break the Worldwound oath about it they might do it and it's not worth the risk (is this bad decision theory? she's not sure)
Keltham could ask someone to bring him all of the deployment, logistics, casualties, honors awarded, disciplinary actions, etc., records for the Worldwound and for the Kuthite war. Maillol will hate this plan because they're classified, but it seems pretty impossible for a Conspiracy to manufacture on short notice. Rejected because: only works if Keltham thinks of it.
Keltham could HANG OUT IN AN ANTIMAGIC FIELD so he stopped having to worry about mindreading. Rejected because: she has already pushed pretty hard for antimagic fields and he's ignoring her and if she suggests it again he will probably conclude that the Conspiracy has a way around antimagic fields.
Keltham could ask to visit Hell, where Asmodeus can probably protect him from the interference of other gods. Rejected because: the Conspiracy could take him to some other place under their control instead; she can't think how he'd verify he was really in Hell.
