Who spends a long time silent.
He is not, in fact, used to being offered his wildest dreams.
And an Atonement. He's also been offered an Atonement. There is a sense in which Razmir regrets his decisions, but it's the specific sense that he regrets that the world sucks enough so that the right thing for himself to do screws over so many people. He does not seriously think that, instead, he should do what does not serve his interests. Thassilon was not founded on the idea of people serving each other, but rather on the premise that everyone who could should learn magic. He has learned magic - he is literally the only Runesage alive - while they are a collection of ignorant savages, and really the answer is clear.
... His wildest dreams are not, in fact, to become a god, though; he's pretty sure of that. Whenever he imagines what he most wants, his most implausible desire, it is to wake up back at home in a world where he is completely irrelevant and completely replaceable. Axis is honestly as close as he can come, and yet he has spent the past decades desperately trying to escape it.
Why didn't he? The spite of the gods? Dreams of grandeur? The desire to outdo the Runelords, and prove himself the greatest wizard ever to live? None of these sound right.
He is pretty sure that it started off with wanting not to die and go to Hell, and also to fix the world, which was dumb. He is also pretty sure it didn't have anything to do with wanting other people not to go to hell. He's not that dumb.
But this is a very simple offer. He might make Lawful Neutral purely from donating his secrets to Lastwall; if he did, Iomedae would, obviously, pay him, because She wants to incentivize future defectors. And He's already old;
And yet, he does, in fact, want to be a god. He's not sure why this drives him so much; why fading into the background in Axis is so impossible. But he is sure that being a ninth-circle wizard is not enough power, and that he needs more power than this for his goal of... becoming a god? Rebuilding civilization? Constructing an Age of Glory?
- It doesn't matter.
"Crafting custom magical items is not difficult for Us." Technically, remembering how to do so is not that hard; His only limitation is that His nation is already spending more than its income thanks to the fraction of its budget that is spellsilver imports. "And if Laswall will give Us Ustulav, their price is fair." He might need to reinvent one a customized magic item for road-building, but doing it with sheer pressure would be... not all that technically complicated? Just a very large set of Telekinesis spells. And constructing an impossible road in a night is really good for looking like a god.
(Razmir is not, in fact, thinking about the economic concepts of 'opportunity cost' and 'comparative advantage' here at all. The question 'should I solve this impossible problem with my favorite solution' has not occurred to him; he skipped straight to 'how'. This is one of the reasons Razmiran is broke.)
