"Can he? If I say 'are these demons vulnerable to cold iron', perhaps, but if you don't have wizards enchanting objects will he know if they're vulnerable to axiomatic weapons or holy ones or no such thing?"

"Not necessarily reliably in advance of testing, but enough to give us an idea of what to test."

Nod. "I should at some point prepare the orison Detect Fiendish Presence and see if the local examples count."

"I'll be interested to see the results."

"Well, you can't directly, but I can tell you about them."

"See in that indirect sense, yes."

"Is it generally pretty doable to locate Evil beings around here? They are little in evidence during the day but maybe if they're overwhelmingly vampires that's why," he remarks, glancing around.

"Overwhelmingly vampires, and frequently nocturnal by habit if not necessity even when not vampires," she says.

"Huh. Do they have darkvision?"

"Vampires can definitely see in the dark much better than humans, and I'd imagine many others can as well but I don't know statistics offhand."

"Darkvision's a technical term, several species on Golarion have it such as orcs. It's colorless and short range."

"I've never been closely enough acquainted with a vampire to ask how well they detect colour at night. I'd guess they do detect it, but that's just a guess."

"And they seem to be able to see farther than, say, sixty feet?"

"Yes."

"Then it's probably something else, which I suppose is unsurprising."

"It's interesting that things on Golarion are so much more... regularized? Many different species having the same darkvision."

"I think they have different ranges but a hundred and twenty feet is on the long end. It meant there wasn't much point in putting a half-orc soldier on a parapet for night duty; they'd need light to see far enough to be useful anyway."

"So what were you up to, in the far north on parapets?"

"Holding the border against demons that tended to enter via a portal to the Abyss. It was closed recently by some archmages, though, and I arranged for formal discharge when one of them was installed on the throne of my country and her party member declared a 'constitutional convention' and wanted church representation."

"The Abyss being... one of your known and limited number of planes?" she guesses. "With demons in it?"

"The one demons are from, yes. There are other evil outsiders, though, demons are the ones that are also Chaotic."

"The translation magic is having an interesting time with all these terms for different types of beings. I guess it shouldn't be a surprise that your system of categories and ours are unrelated and don't map well."

"It's slightly surprising, you have meaningfully similar vampires, though not identical ones, and that's an odder match between planets than would be the various outsider types."

"Because in theory the outsiders are from other planes and don't have a particular association with any given planet to begin with? Interestingly enough, the local style of vampire is also supposedly from another plane, at least to begin with. Any vampire you're ever likely to meet will have been turned on Earth."

"But the infection's from elsewhere? Interesting, I don't know if that's the case on Golarion or not but they are at any rate separate strains."
