Cam is dipping a grilled cheese sandwich into a bowl of tomato soup when he feels the summons. He goes ahead and grabs it. Doesn't even drop the sandwich.
"The circle is necessarily bloody - what, do you think I enjoy getting this stuff on my hands? - and is not intended for summoning anything. I wasn't aware that summoning demons was even possible. Is this the part where you rip out my soul and turn me into a slavering were-beast?" She raises an eyebrow.
"Not my style. Usually this is the part where you want some medium-sized material good and offer me a list of your favorite authors as payment. This is clearly not usually. Unless you've been living under one hell of a rock which has had a few centuries to generate languages I've never heard of among other peculiarities."
"Well, there's another one the Victorian priesthood got wrong, then. Hello, mysterious demon. My name is Isabella Katarina Markova, but you can address me as the Lady Markova - or Isabella, since I highly doubt you count as one of my subjects. This - " she waves vaguely at the surrounding walls " - is my castle. Now that the introductions are done: What sort of books do you like to read, what material goods are on offer, and are there any other issues I should know about?"
"Now hang on a minute, can I get more detail on where I am than 'your castle'? Not that it isn't nice, or anything, but the last time I was summoned it was to a world where this language we're speaking did not exist - at least not as anybody's native tongue - and also everybody knows you can summon demons in lieu of shopping if you want."
"That would be rather unsettling. However, the question of our current location is somewhat of a difficult one to answer. Perhaps I should just start listing nations and other locations I know. Grand Victoria, Mori, Lupinia, Oceania, Ulvenwald? Are any of these familiar to you?"
"This isn't 'you live under a rock' territory, this is 'you live on a different rock, in a different universe'." Pause. "Which is fascinating! Tell me all about your rock."
"I'm most familiar with Grand Victoria. I was born there about seventy or eighty years ago, now, but I've kept up with the times, more or less. Grand Victoria is a mercantile empire, with colonies in the south and west. They used to have a major colony in Ulvenwald as well, but it attempted a revolution and collapsed. The state religion is Taifide, the veneration of the sun and the Empress Hikari Gloriana's line as its mortal agents here on earth, in addition to standards of proper ettiquette and behaviour. There's also a smattering of folk religions, which are generally looked-down-upon but not exactly heresy. Victorian manufacturing is the best known in the world, being the only country with truly interchangeable parts: they are especially known for their airships, which are exceedingly fast and long-range compared to any of their competitors."
She spreads her hands. "Should I go on, or would you prefer I gave you some books from my library?"
Isabella steps out of the room through a finely-fitted oak door with brass hinges.
A moment later, Isabella returns, bearing a small sheaf of cards in neat handwriting.
"Please, be careful not to damage these: I wrote them myself."
She offers them to the demon, then looks at the chair.
"... What material is that chair made of, exactly? It seems organic, but at the same time not. It's almost like someone took 'essence of chair' and made it a thing, that's how subsumed the material is to the design. Does it even have fasteners in it?"
Cam glances at the notecards in her hand, then duplicates them. "No need to hand over your originals. Chair's plastic, and why would I bother with fasteners when I made it from scratch?"
"Plastic, hm? I've never heard of the material. Is it always like this, or only when demons make it?"
"There's lots of kinds of plastic. It can be molded in single pieces like this, although plastic chairs that mortals make often do have fasteners because they're easier to pack and ship in pieces."
"That would seem to make sense, yes. You say that plastic can be molded, like cast-iron. How pliable is it? How is it produced?"
"I don't actually know much about the manufacturing process, because why would I, a demon, bother to learn about a manufacturing process? It can be just about arbitrarily flexible depending on the kind." He makes a small square of plastic wrap and folds it in half a few times.
"It's almost like a fabric at this thinness. How fascinating."
Then she suddenly straightens from her lean inwards, the movement almost a start.
"One moment, I've just realized I'm being a terrible hostess. Would you care to have some tea and a better-appointed room? This is intended as a ritual space, so I keep it quite bare: one of my parlors or sitting-rooms would likely be much more comfortable."
"When I want tea, I have tea," he points out. (He has finished his sandwich since she's been gone.) "But I'm fine with relocating."
She smiles, then opens the brass-hinged door again, revealing a distinctly different room from the last time she did so: rather than stone hallway, the room behind the door is a small parlor with a hearth and a pair of tables, one of which is set up with a small set of stone game pieces on a checkered board.
The other, larger table sits in a wide alcove, lacquered wood reflecting the faint glow of the moon through the three large picture windows. An observant person might notice that they can see the moon three times, once through each of the windows: indeed, each of the glass panes opens onto an entirely different landscape.
Isabella pulls out a chair for her guest. "Please, sit, and if you want tea I'll be happy to fetch it."
"Sure, I'll try some local tea," he says, following her and sitting in the chair offered. It's not designed for his wings, but he manages. He does indeed look out the window. "Are those screens? No, probably more magic, isn't it, you haven't invented plastic and probably don't have monitors."
She sighs.
"Oh well."
Making a small hand-sign to one of the dolls that followed her in - tea - she settles into her chair, her eyes lingering on her servant just long enough for it to affirm her request.
"While we're waiting for tea, did you have any other questions you would like to ask?"
