Cam catches this summons while he is in his garden, because he has come to the realization that he finds bonsai really boring even if you are skipping a lot of the steps with conjuration and he does not want to continue to maintain this tiny tree enough to be at home for it for the next while.
"...I'm not sure I'm familiar with the kind of plants around here. I haven't seen any yet. I can just make things by magic. Quite fast and as much as I want, when I'm at home and there's no summoner involved."
"Is your home an infinite dimension with infinite energy and many other beings like you that can use that infinite energy to create whatever form of matter they want?"
"It's an infinite dimension. I don't think I'd describe it as having infinite energy, the place isn't powering what we can do, we are just the sort of thing that can do that and also we live there."
"So... if you make something here... you're not getting power from that dimension to do it, or something? You're not, like, connected to it through an interdimensional portal kind of inside you?"
"No and no. - there's some technology that could act sort of like I was telekinetically controlling it, I guess, and I can, like, set things on fire."
"Huh. So you're kinda like plants but not really. Do you have some kind of energy you use up?"
"There's two ways. They can just let me do whatever I want at will, that's called snapping a binding. The other way is... whatever they wrote into the circle, which I couldn't read since it was dark."
"Unfortunately we're not telling us what we wrote in the circle. We know a bit, but the us who know more are hiding now.
"Can you make... water?"
"Sure! I've been tempted to make it rain here to see if the desert has any seeds waiting for a once-in-a-century storm or something."
"Oh, we don't have flora at all. All the water on this planet is suuuuuper underground, we have a ton of cave systems! It's where most of us live most of the time. We never let any humans explore them, though. Gotta keep the mystery. They don't even know about it."
"Huh, there has to be, like, some atmospheric water vapor. Maybe not enough to ever form clouds but that one cave was open the surface and some of y'all did not look maximally watertight as organisms go, even without biting each other in half which certainly doesn't help with that. How do you stop humans from exploring caves?"
"I was sort of expecting you to say that but I was hoping you'd be less cheerful about it."
"We learn many new things when we eat ourselves. Things that we already knew, and then more of us know."
"Is that your principal way of distributing knowledge within the hivemind? - if anybody eats, uh, enough, I'm not sure how much would be enough, of whatever subset counts as my summoner, I will probably vanish back home."
"Oh we don't think so. We're not individuals. If anyone's a summoner we all are, we think."
"...well, I have no idea how that will interact with the bindings situation but you could test it, if you wanted."
