"So what's the occasion?"

"It turns out there are more worlds than the one we're usually summoned to. This is a new one, it has vampires and witches and many varieties of demons which are not daeva. It's also 2005 and summoning is not known to be a thing."

"Wow."

"Welcome to 2005, population: things that go bump in the night."

"So I'm just the test case?"

"You are just the test case. Want to change this donut into a lemon creme filled one in exchange for this chocolate one?"

"Sounds good."

"Now you have to agree to the deal," Ellie says to the summoner.

"And I don't have to repeat the terms of the deal?"

"You can, you can also say 'the deal as stated by Ellie', as long as we're both talking about the same agreement."

"What's the magical upshot of my agreeing to this deal?"

"I can leave the circle to do the thing, take the reward, and then I can go home. If we don't agree I just sort of have to stand here until you dismiss me."

"Next time I'll leave enough room for somebody to sit," says the summoner. "The terms of Ellie's deal are agreeable to me."

"Done and done! One lemon creme for you, one chocolate for me. Feel free to call me back any time!"

"Now you dismiss him."

"If I call you back what are you likely to want?" the summoner asks him, ready to write up a list.

"A book about vampires. An orchid. Maybe an authentic witch's hat."

"How are you going to verify the authenticity?"

"I'll put it on and see if it makes me feel like a witch."

"I'm not sure even the real ones do that."

"On the other hand, this world's magic apparently doesn't work for her. So you may yet be in luck."

"I haven't done the hat experiment, either, so maybe I'm wrong."

"As long as there's not no hope, there is some hope. And that's good enough for me."

"Okay. Thank you very much, I will see about your wishlist." Dismissalllllll.
