"That's a week of realtime, two weeks of demiplane time, and those two weeks may matter considerably. In particular, they matter for whether or not I have an incentive to destroy Egorian or all of Cheliax to prevent the ensoulment of my children, or as many of those children as possible, or if I'm able to advance other plans to a point where it's clear that Golarion and Cheliax will end up being an acceptable place for children."
"I'd like to buy your Wishes to enhance my Intelligence, Wisdom, and Splendour. I want to rent your artifact headband for at least a month. I will not offer you thousands of Wish diamonds in exchange, because I don't want them proliferating all over Golarion just yet. I will offer that you may go on the trip to the City of Brass that I was previously planning to take with Ri-Dul, where, I've read, many Efreeti can readily cast Wish given a large enough diamond for it. I'll send with the Wish diamonds and other payments for you to buy +5s to all six of your abilitystats in the City of Brass. In the event that I cannot fulfill my side of the bargain in a timely fashion, because the diamond synthesis method failed to scale to Wish diamond size, I will endeavor to pay you back the reasonable value of fifteen Wishes and the headband rental whenever I can. Unless I am dead and unresurrectable for any number of reasons, in which case you will have had unremunerated bad luck."
