Yeah, ey figured this was going there. Time to play the game of Make All The Complexity Be In Keltham's Questions And Not Eir Answers. "Yes."
Keltham actually hears an answer from Griffie this time.
"Abyssal is as Irret says. Seal-scrambling is as Irret says. Societies know how to handle these things, and smart devils, it's not extra-hard for them. Irret's society has the Great Library of Harmonious Scripture and a god is focused on running it and lots of people work on it and it catalogues lots of things including stuff for avoiding threats like Abyssal. That department exists and Irret has been told to report to it under those conditions."
That was all of Irret's claims, except for the claim that societies could not only handle Abyssal and seal-scrambled documents and understand the dangers of smart devils, but understand things in that reference class. Which suggests that there's something in the reference class Griffith is aware of, and Irret isn't.
"Are there hazards you don't think Irret's assessment accounts for?"
"Well, one such instance is Fulgati Psychopomps. They attack civilizations that they believe have gone on too long, and almost everyone just … reflexively forgets them once the Fulgati isn't right there anymore, because Fulgatis are too horrifying to think about. They typically conclude it was just a natural disaster."
"Well, that's terrible. Not worse than Hell, but terrible. Irret, would you say the Upper Planes know how to deal with Fulgati stuff?"
"They're also just really hard to fight, but the forgetting thing yes? We have people who are resistant to that kind of fear and we know to listen to them."
"So there's another thing that isn't Fulgati and isn't Abyssal and isn't devils and isn't seal-scrambled information."
"Well, there's actually a lot of infohazards depending on how broad you get? There's snakes which hide in text, some of which are magically created usually to attack an unlucky 'reader', and that's fairly representative."
"You must realize that your pattern of question-non-answering is a terrible way to avoid leaking information, right?"
