"We do have the option of swearing to Asmodeus of the truth of those things that we might tell them, by which we ourselves have come to suspect this. It doesn't do to overuse that option, lest they come to expect it and suspect all unsworn is lies. But it is an option, when you need to tell a fellow Asmodean something ridiculous and true - if you are about Asmodeus's own work, that is, lest you invoke His name for only your own benefit."
"There is also some degree of corroboration, if the Queen is willing to declassify it for them."
Jacint Subirachs hands Sevar a brief report written in the hand of and under the name of Abrogail Thrune, marked with nearly the most extreme possible Crown seals and penalties.
The Queen notes that she has now reviewed the most recent batch of Project Lawful reports, including Sevar's apparent price in Hell and Keltham's speculation about what younger devils may not be allowed to know.
The Queen at once set aside all her other work to inquire certain matters separately of Lrilatha and Gorthoklek. And then summoned a series of devils herself, up to the most powerful she could summon without that being a grave matter.
The results show that the most powerful devils the Queen can lightly summon - admittedly, not mighty ones by Hell's standards - seem entirely ignorant of matters like whether there are twenty-one or twenty-three pairs of packages of heredity-specification in a human body. Lrilatha answered correctly, but also answered affirmatively when asked if she had come by that information by way of Keltham.
Gorthoklek, who is nearly royalty of Hell (though, the Queen notes, relatively young for a pit fiend), cannot answer; and if Gorthoklek is shown the information by way of Keltham, he can then answer regarding what he has seen in the report, but he still cannot answer the question on his own terms.
The Queen speculates that the price for why Hell can seemingly back Cheliax to a greater degree than other Outer Planes back their mortal worshippers, is that Asmodeus and His highest slaves are extremely constrained in what they tell those beneath them in Hell who hold more commerce with mortals. Such enforced ignorance, in exchange for power in the mortal world, seems not discordant with His aspect of tyranny.
The Queen speculates that there is however no prohibition against a soul being allowed to retain and use such knowledge that it learned in life. For if this is not so, Sevar's price in Dis seems inexplicable.
The Queen inquired of Gorthoklek upon all of this matter, and Gorthoklek said nothing to all of it, nor encouraged any of it, but neither did Gorthoklek call it prohibited.
