Bella orders the ingredients and blanks for another dozen. "It depends on where you draw the line between 'knowing' and 'having'. Witchcraft is most clearly the second; others include sorcery and elf magic and dwarf magic and a little borrowed wizardry and unicorn spells and stuff."
"I can see why you became a magician. I'd be one, if I lived in your world."
"I almost want to visit. I probably would, if I had a sure way to get home again later."
"I don't think I can guarantee that. I don't know how to finagle interdimensional travel on a reliable basis. Sorry."
"The bar itself and your healing trigger and protection amulets are plenty nice already. Can't have everything."
"Stop or contain all the really nasty problems in the world, then start going down the list of everything from most to least interesting?"
"Today is the best and most interesting day I've had in months." She starts humming a little tune.
After a while, "I'd feel better if I bought something for you other than 'be a good deeds target'. Even if it's just buying something."
"If you really want to, there are some ingredients for spells that are inconvenient to get for reasons other than expense? I don't want to cut into your useful souvenir budget too much."
"I'm cutting very deep into my bank account on the assumption that I'll be able to make most of it back through clever useful-souvenir-exploitation. Another two hundred Svalten won't make that much of a difference. I'm spending at least ten thousand. Saving up several years of combat pay pays off if you need money suddenly."
Bar provides currency conversion. Bella provides a shopping list. "But I might think of something better to do with spending money here, so hold that until I've had longer to think?"
Of course.
"Bar, I think I'm good on stuff for now. Reading about tech I don't particularly understand yet is only interesting for so long. What have you got in interesting otherworldly fiction? Something lighthearted, an adventure story."
Bar presumably provides, and she reads.
And the otherworldly magician performs otherworldly magic.
She heaves up a large sled holding far too much stuff for an ordinary human to comfortably lift and walks toward the door. "Perhaps we'll both find this place again some day. Good fortune to you!"
