Bar supplies books. They look.
They don't find anything better that he can do with one spell.
"Do you know if there's anything I can do to - help my chances to get another door?" he asks, while he's reading another book to shove as many spells into his head as possible.
"There's - superstitions. I don't run up a tab, even when I'm really tempted - but I don't know if it actually helps."
"... I'm tempted to say, 'use my tab' and possibly not be able to come back, but that potentially loses you the hex entirely."
"I don't know if it helps. Bar doesn't know either, she doesn't do the door."
"I'm willing to," offers Edarial. "Either way it would be helping you. Potentially, in one case."
"How about - tell Bar that I can use your tab? And I'll try not to, but if I'm ever - if there's a bad month at home and I can't get food there, either, I'll use it instead of opening mine?"
He goes up to Bar and informs her that Shell Bell can use his tab.
Of course. Do you wish to limit how much expense she can accrue on it?
"I don't know how much money you have. I don't even know what kind of money they use in your world," Shell Bell points out.
"I'm nine," points out Edarial. "I don't have money. But I can put a limit to it if it helps?"
"Yeah - like, some people have little tiny currency and some people have big currency. Six of somebody's something might be worth a billion of somebody else's something and I don't know for yours."
He thinks for a bit, does a bit of math in his head, and names a sum that's actually quite reasonable for a nine year old.
"I'm going to stick around for a little and try and get more spells. But then I'll need to go grab food."
Studying ensues, and then his stomach grumbles, and it's time for him to go.
"Good luck," he tells Shell Bell. "I wish I could have helped more."
"It's okay. You fed me and now I have a safety net and I know you wanted to help."
Another nod! "And hopefully I get another door and can get you the hex."
