"Okay. So, your dad is a god called Yog-Sothoth, and you were trying to summon some... hornets? What did you want with hornets?"

"They're not sapient--they're not actually hornets, either, they're just called that--and I can kill them without getting hurt too badly. We ran out of cows months ago." 

"...there's just... a summonable supply of hornets, somewhere? - is there a specific reason you ran out of cows and can't get more, what's your usual means of support here?"

"Grandfather had some money inherited and he used to use it to buy cows but--there wasn't a lot left, and--things...happened. We still have a little money, enough for Wilbur to eat, and if I can eat things like the Hornets he probably can too if it comes to it--" 

"As far as we've been able to tell the Hornets are part of some extradimensional ecosystem. Or--transdimensional, perhaps, there are stories in the Necronomicon of things like Hornets and Hounds of Tindaloo being able to cross over into our world by themselves." 

"And you couldn't get a big enough herd of cows going to sustain themselves before too many things had happened. I see. Is there any income going on here at all?"

"...No." 

"Why not?"

"The townsfolk don't like us. And moving Lucy safely is a dicey prospect." 

"Because of footprint-related concerns?"

"...And I'm...not safe to be around when I'm so hungry I can't think straight." 

"...have you ever eaten a person?"

"I didn't mean to."

"Christ. Okay. I'm gonna register my disapproval for your unsustainable animal husbandry and make you all the megafauna you want and maybe your own cottage vat meat operation so you can open a little butcher shop."

"The herd was sustainable until I got so big. Grandfather didn't know I was going to get so big." 

"It may be that nobody could have done any better but the time for emergency measures was the first year there were only as many new calves as you'd eaten cows in the last twelve months." Sigh. "I am going to... look up a ten minute presentation on American history, go through the highlights up until 1928, and see if there are any discrepancies that don't directly have to do with extradimensional hornets or deities, sound good?"

"Alright. Even if we don't find anything, you might want to compare it against a history book from our world, or someone who knows more about history than we do--relatively few of Grandfather's books were on history, and most of them were old, so anything between 1860 and 1913 I honestly couldn't swear to." 

"That's a good idea. This is just an overview against common knowledge." He produces an item made of metal and plastic and glass about the size of a small leek and turns it on, projecting a rectangle of light into the air. He looks at the light and it moves around while he nibbles his lip thoughtfully and finally pulls up what he wants. "Here goes An Abbreviated American History."

It's very abbreviated, and Cam only continues for the first two-thirds of the content, since after that it's past the current date. There are pictures.

"What is that?" 

"The Washington Monument."

"...That looks very small and portable to be a monument." 

"I think he means the picture. The obelisk. I think I saw a picture of it once." 

"Oh. I mean the, uh, device." 

"Oh. A computer. They are a futuristic device. This one requires brain surgery to operate."

"...Why are you using a device that requires brain surgery to operate? Can you conjure that but not books?"
