invented to keep out the cold
Unlike Mika, her foot does not have a bad case of rat tooth to the heel!
She runs home, gets the contract she knows her mother will sign written up, and about midway through actually mentions the offer to Mother. Fortunately, she was not mistaken any more than the first vision showed — Mother thinks she can find a buyer at market rates in not too long, she'll take the ring now for... nineteen thousand five hundred silver shields.
Tencednil would guess Mother could probably do twenty thousand silver shields and still make a reasonable profit, but they are kind of rushing for a buyer and it's mostly the other explorers who are losing out. And even then, if they had to find a buyer of their own who didn't really trust them and all that, it would most likely cost at least the fifty gold sails they're losing here. This way, everyone makes a profit and nobody's really complaining about it, so it's not fundamentally a betrayal of the shared endeavor. Contract: written up! 19500, split into four accounts, acceptable to party 1, signed here, conditional on a Truthspell, the accounts to be listed by parties 2, names here, one signed. All looks good, pretty much the same as the contract she remembers from the most recent vision.
She runs over to the bank, and... contract drafting takes time, but much less so when she knows exactly what she's writing. She gets there five minutes after the hour mark, and runs the last block so she shows up out of breath.
"Sorry, that took longer than I realized, writing things formally is slow. Here, take a look. Does this work for all of you? Signatures and account numbers go here."
