Zuragazh leaves the room.

The imp, which has been obediently silent since the conversation started, stands up from where it's been sitting curled up in the corner of its lantern. When the little dragon is looking in its direction, it presses its nose to the glass and pulls a silly face. 

The little dragon considers it for a moment, before deciding it can't hurt, and pulls a similar face back, facial structuring warping where necessary.

Oh, excellent! 

The imp jumps up and down laughing, then starts pulling more weird faces to see if the little dragon will copy those. 

They certainly will! They're happy to give the imp some entertainment, their job doesn't seem terribly fun and the little dragon imagines they can use some.

In this way, they will pass the time quite pleasantly until Zuragazh comes back. 

When the imp hears his footsteps outside the cave, it squeaks and scrambles out of its latest silly pose—bent over backwards in an arch, looking at the little dragon upside down. 

The little dragon (who has ended up a bit un-dragon-shaped over the course of this game) rights themself and returns to their simulacrum-shape of Zuragazh, though not with the hurried haste of the imp, and returns their gaze to the returning larger dragon.

Zuragazh pretends to ignore these antics as he walks in.

He has a bag slung around his neck, the better to transport the various magical instruments he's fetched from his workroom. The first one he pulls out looks somewhat like an oversized magnifying glass, with a long curved handle designed to be held by a dragon's hand. 

"I'd like to examine both you and your berry through this lens," he explains to the small dragon. "It will let me observe some of your magical properties." 

"Observe at will. I can take a different pose or shape as well, at your request." The small dragon retakes the gift-berry from where they set it on the ground while playing with the imp.

And Zuragazh will hold the lens up to his eye and squint through it.

That...hmm. That is a lot of magic. It's completely unlike any magic he's ever heard of before, and therefore his lens can't tell him much about what it's doing beyond existing.

He can see, however, that whatever the little dragon meant by 'souls', it doesn't correspond to what Zuragazh thinks of as a 'mind': the little dragon is very much not composed of ten trillion separate minds by local standards. They definitely have...more mind-substance than is usually present in a single person, by quite a bit...but it looks to be all one consciousness. That makes some things simpler, at least. 

"Interesting," he says aloud. "Would you mind putting the berry down again, so that I can see it more clearly in isolation?" 

"Not at all." They'll place it back down at one edge of the circle and move to the opposite.

Looking through the lens, It's clear that the berry has some of the same sort of psychic substance as the little dragon, and is filled with the same magic, though both in vastly smaller quantities. Notably, the berry's mind-substrate doesn't contain anything that looks like a proper mind, but it's not totally blank either. It seems passive, but not static. Quiescent, maybe?

Very interesting. That matches up with what the little dragon has said about the berry, as far as it goes, but Zuragazh has no way of knowing whether they were telling the truth about its effects.

"Is it particularly costly for you to produce these berries?" he asks while considering his next move. 

"Not in the slightest." The little dragon replies, raising a claw, closing it, then opening it to reveal a clawful of additional berries (inspection of which will indicate the same psycho-magical readings as the first).

"I see. Are these particularly tailored to me, or to dragons in general, or would they work exactly the same for any creatures that ate them?" 

"I've taken the overall architectural and biological trends of your brain into account when designing the knowledge-imbuement, so I can't promise that specific aspect will work as quickly or as perfectly in lifeforms with radically different brain-structures from yours. Otherwise, yes, it should work just as well for anything that can absorb the fruit's juices."

Zuragazh nods.

"Could you make one tailored to, say, this imp?" he asks, tone carefully one of idle curiosity as he gestures to the lantern still sitting on the floor near the circle. 

(The imp squeaks.) 

"To make one to equal specificity I would need to scan it as I did you earlier, but given that, yes I could."

"For that, you just need to touch it briefly, correct?" 

"And its consent, or at least non-resistance."

"Hmm."

He looks at the imp. "Do you want to be able to change your body, as they do?" he asks it, indicating the little dragon. 

The imp nods. 

"Good. I'm going to let you out of the lantern so they can touch you and make you a personalised magic berry. Don't smudge the chalk, and don't step inside the circle: just put your hand across it. Do you understand?" 

Nodnodnod goes the imp. 

Zuragazh flicks open the catch on the lantern so the door opens for the imp to climb out. It scurries up to the chalk circle containing the little dragon, stopping before its toes quite touch the chalk. Turning away and screwing its eyes shut, it determinedly sticks its arm out over the line. 

The little dragon steps up to where the imp has reached into the circle and taps its hand with a claw. Depending on the imp's magical sense it can probably sense some kind of magic passing through but not touching or acting upon its body, and if Zuragazh uses the lens to observe it he will likewise find a pulse of the same magic which suffuses the the little dragon and the berries, lightning-quick, expanding out from the point of contact and through the imp's body.

The little dragon now knows the imp's form, at least on a physical level, including its brain. Unless there's anything particularly ethereal or ephemeral about its physiology (admittedly a real possibility), they will then create a new berry with the same magical and psychic payload translated into the imp's format, which they will also make to have a noticeably different shape and color for the sake of clarity.

The imp flinches at the pulse of magic, but it doesn't pull away, keeping its arm stuck out for a few more seconds until it sheepishly opens its eyes and notices the scan is over. 

With a glance at Zuragazh for confirmation, it picks up the new berry and hesitantly takes a bite, bracing for another wave of unfamiliar magic. 

The berry is sweet, and tart, and has complex taste and aroma, though the imp may not have the experience to compare the flavor to, though it is broadly pleasant. This flavor is indeed accompanied by another wave of magic, though it's slower and less sudden than the scanning pulse, beginning more as an almost physical tingling in the imp's mouth, which spreads down its throat and into their chest, where it becomes a gentle warmth which then spreads outwards through its whole body. When that warmth reaches its head, a trickle of new-yet-familiar sensations and intuitions appear in the imp's mind. It now possesses the full complement of the Fallen One's power and prowess with the Coils.

Wow, that sure is some weird magic! The imp shivers. 

It mentally pokes its new intuitions. So what can it do with this thing, anyway?

So much is possible! If the imp is feeling tired or achey anywhere, for example, the Coils are ready and able to cure that right away. If it wants to change how it looks, it can! If it's ever wanted to be in two places at once, or even more, it can now, though it'll need to divvy up its biomass between all its bodies. If it finds another creature with an interesting ability or attribute, it can scan it the way the Fallen One scanned it and learn how it works and how to make it itself, and learn all sorts of other things as well. With a willing partner they can go so far as sharing memories or skills. That's really just the beginning, too, there is so much the Coils can do.

The imp starts by clearing up all the little aches and pains from being sat on a stone floor and before that being stuck in a lantern.

Then, with a glance at the little dragon to check they're watching, it tries turning the bones in one arm soft enough to bend like rubber. Waggle waggle waggle rubber arm! It giggles at the weird sensation.
