In a bar between universes, watching the stars explode from her booth, there is a young woman drinking a steaming mug of creamy tea.
"Recently I've been working on intent-triggered wards and I could maybe do one that'd make you immune to all magic except when you chose not to be. It'd be kind of complicated, besides not having been tested against imps, and the choosing to turn it on and off might not work well, and it's very likely not to actually work if their magic is much like magic I'm familiar with because it wouldn't protect you from, say, someone magically lighting everything around you on fire or magically accelerating a rock toward you."
"Would it affect my paladin powers?"
"I do not know what paladin powers are."
"We get various blessings from - in my case - the Winter Light, like the ability to heal ourselves and our mounts, strength and endurance, the ability to speak to anyone, the ability to bless our weapons and armor..."
"Okay, first of all, that's the kind of thing that matters to making your weapon more durable, I don't want to interfere with your blessings. Second, I maybe want to hire you to come visit my world and do your healing there, if the Winter Light wouldn't mind and depending on what kind of healing it is."
"It's just ourselves and our mounts. I have basic field medicine training for other people but can't heal them any faster than that."
"Well, no sense in hiring you, then. I - could do it so it wouldn't affect that, if I knew enough about the Winter Light to distinguish them from anyone else. Or I could do less comprehensive things."
"Distinguish them like how? Would reading the Precepts do it?"
"I also do not know what the Precepts are - the last time I met someone with powers from a god, I stepped into her world and prayed and had a conversation with the god in question, and it wasn't for that reason but that'd do it - I can go by genetic relation or physical form if that's... applicable... and separately I'd love to read the Precepts, what are those?"
"The Precepts are the holy book of the worshipers of the Winter Light. - there are a lot of Lights and they're not opposed, Light is Light, but different ones are favored by and favor different peoples and my order is blessed by the Winter Light. There's no physical form or - relation."
"I just need - something other than a name, because, I mean, I could decide that I want to be called the Winter Light from now on and that wouldn't affect whether anyone wants me doing magic to them. An example spell or an enchanted object would do fine, or the Precepts might do it if they contain the right kinds of information or if I had a copy the Winter Light had personally written."
"My swordstaff is blessed by the Winter Light."
"Already? Then yeah, that'll do."
She pats it. "It doesn't take very long to bless a weapon, it would be silly to send anyone out with one that hadn't had it done."
"I had the idea it was something you'd have to redo regularly. Anyway, does it have any other things about it that aren't obvious at a glance, like if it needs to be able to change shape or come apart or anything?"
"Well, if it breaks I have to repair it, but it doesn't detach or change shape."
"Well, it won't do that anymore. - And if it somehow did, any spell I cast on it would also break, that's true of all magic where I'm from."
"The blessing would too, we need to re-bless weapons that have gotten seriously damaged."
"Makes sense. I ran into a world once where broken magical things could be harvested to make magic things but I don't get the impression that's the norm."
And he'll make the swordstaff indestructible. It wasn't that useful a conversation but he at least articulated his problems in ways that might be clarifying and got a book rec.
"Thank you! Are there more things you wanted to know?"
"A lot but I'm not sure what to ask - maybe the Precepts will make it clear but I don't even know what a paladin is..."
"Paladins are people sworn to the service of a Light. We have some powers and we keep them as long as we keep our vows. Obedience, chastity, piety, and service, in mine, though different orders have slightly different sets."
"...Chastity? Is that something that will make sense to me if I just read the Precepts?"
"Possibly? Do you not know what the word means or why we'd do it?"
"The second one, I think."
