There is a book held open with a rock and a wooden stake; and next to it a messenger bag; and beside these a teenage girl, painting goat blood onto the floor of a crypt.
"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!"
"If I call you back what are you likely to want?" the summoner asks him, ready to write up a list.
"On the other hand, this world's magic apparently doesn't work for her. So you may yet be in luck."

"Media recommendations. We should see if there are any significant differences due to the divergent magical history, those would be valuable."
"Yeah, otherwise I feel like being from the past will handicap me terribly."
"We should compare history, find points of divergence... I might have to just repeatedly summon demons until I find one who's bored, bootstrap from there, if you don't have reliable history memory off the top of your head..."
"Broad strokes, yes. I will likely not be able to tell whether a given artist or author has a counterpart there. Repeated summonings could be a viable tactic, if we leave off the standard gag."
