It's not the right time, is the thing; she had a plan, and now instead of being summoned right into it she's being summoned into a fairly miserable fog of uncertainty, and she's not liable under such circumstances to get any shot at Tar-Baphon plus it's much more likely someone assassinates the Emperor or something. 

She still comes when they call her, of course. 

Several hours later a Gate opens to what looks like a lovely six-story treehouse built around a great redwood tree, sunlight filtering through the branches up above, and an astral deva says "come through here, please, I want you out of the way during the siege of Canorate because it'll be enormously damaging to all our interests if you're kidnapped."

"Ma'am, I have a guess about who you are but no real way to check, and I don't know if anyone on this end is expecting me to be licitly relocated or if it would be in contravention of my previous agreement not to try to escape."

"I have their general permission to act as I see fit in the pursuit of our shared aim of winning the war. You indeed have no way to check who I am, but no one who can open a Gate needs to ask you to walk through it."

But you see he agreed not to try to escape.

"Will it dreadfully inconvenience you if I require you to make me, ma'am?"

She drags him Telekinetically through the Gate.

He is now in a lovely library-treehouse. Most of the books are not in a language he speaks but some are.

"Thank you ma'am. What is it you'd have of me here exactly, just that I be out of the way?"

"Try not to get kidnapped. Nothing else is urgent from you." And she Plane Shifts off without casting a spell.

He isn't really sure how to try at that from here!

He will have a look at the legible book-spines, though he is undecided about whether he should touch any of them.

There are some very old history books, and some copies of the Arodenite scriptures, and detailed instructions on the breeding of hunting falcons, and a series of ...romances set on the Isle of the Penitent in which everybody is a rabbit.

If there are several copies of something that is as easily come by as the Arodenite scriptures probably are, it is probably okay for him to read those. He'll take a History and Future, whichever one is least fancy, and start reading it.

The History And Future Of Humanity begins with an account of the wonders of lost Azlant, how mortals built them and how the war that ended up destroying them began, and then the grim centuries of darkness (figurative darkness; the literal darkness didn't last quite that long), and then a series of optimistic projections of what it'd take to surpass ancient Azlant anew. It is thorough and detailed and the first chapter contains a digression into animal breeding, a digression into the superiority of writing systems related to the sound of the word, a digression into the invention of arcane magic, a digression into the making of a kind of food that doesn't translate well to Taldane, a digression into why few women are wizards given that it isn't that they're less intelligent, and a digression into astronomy.

Blai doesn't think he is an Arodenite any more than he is an Abadaran, really, but it's a pretty good book and dense enough to occupy him for a while of being stashed.

She does not return before the time when, if not for intervening events, it would be time for Blai to pray for spells. 

(She's really extremely busy, see.)

Well, he has no idea what plane he's in right now let alone what time zone. He goes to sleep when he's tired in a soft part of the library-treehouse that doesn't look like it might be somebody's bed already - there's a reading nook with enough pillows to be quite comfortable - and when he wakes up he doesn't know if he should be expecting to feel the tug of dawn or not.

When dawn comes on the Material Iomedae is fighting on the walls of Canorate, and has been for sixteen hours. She staggers back from the front lines and into the chapel to ask Aroden for her spells and healing. The healing she is planning to use immediately to make up for the fact she has not slept and also has second-degree burns over most of her body. 

When she closes her eyes and seeks out Aroden there is also someone else there.

Wow, he was not really expecting this. Is this Her, or just... her. Well, if it's the former She's definitely not going to tell him so, because that would be expensive, and it might also be in the latter case, he has no idea what it might be like to be a mortal-for-now paladin trying to grant a cleric spells. He doesn't really need any, if it's hard, he's just hanging out in - situation report, in case Arazni did not mention or if it's after all not Arazni. Individual who is most likely Arazni Gated into his cell, about... ten, twelve hours ago now?... and asked him to walk through the Gate, but he was not really clear on her relationship to the chain of command and he had said he wasn't going to escape but she very kindly obliged him in his Law pickle by telekinesing him through. He has not made any agreements to the effect that he should otherwise not operate under the assumption that she is Arazni and onside and authorized to tell him to do things so he's just assuming those things until further notice and hanging out in her treehouse library now, he's not sure if he should expect it to be in Aroden's realm in Axis or somewhere in Nirvana or perhaps splitting the difference in Heaven; he's been reading History and Future because he hasn't read it before and it seems pertinent. There are as many female as male wizards in the Cheliax he grew up in just like the book says there are supposed to be in ideal conditions, and it is sort of nice to know that this outcome is abstractly desirable and not just a thing you get if you are working for Hell in the process of obtaining it.

He hopes it is not distracting if he has reached Mortal Iomedae and she's having to cope with receiving prayers for the first time? He isn't sure how to pray nondistractingly especially since he can't just repeat anything rote out of the back of the book when he does not have the book to flip to the back of, but, again, he doesn't really need any spells in his present situation, and (s)(S)he should definitely not give him any if this is difficult or inconvenient, and he can maybe even try to commit to not finding it useful information if he doesn't get any spells except he has not quite worked out how to do that in all possible situations especially over long time horizons, and is only mostly sure he can do it in the situation "sitting in this library treehouse reading History and Future". ...if this is Mortal Iomedae then possibly he is useful as a once-a-day high bandwidth possibly-unidirectional free Sending apparatus? If (s)(S)he would like him to bear that in mind as a possibility to follow up on and would like to expressly communicate this and can do so how about, uh, swapping his Spark out for a Mending, hopefully that's lower power than doing any of the other spells in the event that this is draining/distracting/awful in some way, and then also he'd have a Mending and could be slightly less anxious about tearing Arazni's books, which he has not done and does not think he is objectively likely to do, only, they're Arazni's books and she's a demigod. And maybe he just shouldn't ask for any other spells so it's the least informative possible hour of prayer he could possibly be having, but if everything is wildly convenient for some reason he could maybe think of more meanings to assign to spells, just in case Mortal Iomedae finds it costless to give him whatever comes to mind, and then he'd be a slightly bidirectional comms apparatus instead, which seems better, though you'd want an entire phrasebook for this situation and they absolutely don't have one so he's going to have to make something up on the fly and it will probably not be very good.
