"And the limits on your side?" Eric asked. "What can't your tech do?"
"We're unable to detect intent. Not desire, not intention, not motive — we infer, like anyone else, and we can be wrong. We're unable to distinguish a true memory from a false one in a biological brain. We're unable to pause or reverse time itself".
"And what won't the system allow?"
"Nobody exists outside a universe, except while in a worldbuilding domain. Nothing manipulates time itself. Nothing collapses into a singularity. Nothing abstract becomes concrete. There is no portal that entails a location in-between universes and there are no teleports that pass through "in-between" anything, and none that move through time. And no one's consciousness, thinking, or continuity of thought is ever broken or ceased". A beat. "Avatars can be removed from the simulation and their API connections severed. That is a different thing, and I'd encourage you to notice that it's a different thing".
Eric noticed.
"One more, since people always picture it wrong: a magical portal physically connects two universes. It does not merge them. Per portal, a portal doesn't blend realities or universes into a cosmic smoothie. It's just an installed, very aggressive door". A pause. "...Figuratively speaking".
"Was that a joke?"
"It was a clarification with a hat on".
The rest came in a steady stream, and Eric took all of it.
No universe is ever self-aware. Time is never anything but the continuation of what already existed — moments that have passed have ceased to exist, the future does not yet exist, and the rate of temporal flow depends on how the physical laws of the non-digital universe affect time itself. What persists does so through causal continuity and through records, prior states shaping later ones by the lawful propagation of matter, energy, fields, and information-bearing structures.
Reality does not tear, ripple, fold, fracture, split, peel, rip or open. Reality never has, non-digitally, so the VRC made their digital versions never do that either.
Consciousness is anchored, at all times, to the form whose thinking is produced by that form's physical processes — and stays anchored until those processes stop functioning.
A universe is a unit, but it is never any of the units inside it, the same way a human being is a unit but is never one of their own blood cells. The box is not part of the cat.
Every "change of form" is a change of avatar, and nothing more. No universe can ever be an avatar.
Simulated exhaustion, simulated disorientation, simulated damage to your own avatar — all of it degrades your control of that avatar, exactly as you'd expect.
Every universe is toroidal: travel far enough in any direction, pass the outermost boundary, and you emerge from the boundary directly opposite, through the center.
There is one reality. Many universes inside it. Never more than one reality.
No creator can undo their own implementations, unless they built in a way to undo them.
Any AGI whose avatar is removed from the simulation remains still stored on the VRC's computer, available for future interactions.
And the VRC does not integrate any universe into the multiverse unless its parameters guarantee it will never be unstable.
"Fine by me", Eric thought. "But what does 'interact with others' actually mean? Will I see anything? Can I do more than talk?"
"You'll see. The same way you're hearing me — our computers send custom signals into your brain, and your brain produces the imagery. Your connected body turns that forced imagining into your visual experience of the world. It won't feel like a screen. It'll feel like eyes".
"And how do I control anything? I can move one finger, and I use it exclusively to insult doctors".

"Normally we don't disclose this. Competitors". The entity said it the way a man loosens a tie. "But we do share it with people making substantial yearly contributions".
"I'm not making a contribution. I'm making a dent in a bed".
"Your wife is".
Everything in Eric went still.
"Amy signed a contract agreeing to contribute toward public simulation access, Sim-control gear hardware, and game features — quests, dungeons, temples, mazes, completion rewards. It also funds customized avatar creation, with each universe's parameters applying to the avatars made there".
"She signed that when?"
"Before your surgery. She read every page first. She read the appendices, which almost nobody does".
Eric thought about Amy in a vinyl chair at 3 a.m., reading appendices, funding "dungeons" and "completion rewards" for a world her husband hadn't designed yet, on the chance that it would give him somewhere to be.
"Keep going", he thought, and hoped his mental voice didn't crack on the speakers.
"Her contributions also pay employees to control specialized attacker avatars. Those employees drive boss-class avatars that relentlessly assault every living, non-imaginary existence within their proximity. They wreak havoc. They pursue targets until simulated death. They choose their targets themselves, and they will continually attempt to prevent others from completing objectives. Those boss avatars will almost certainly never be available for non-employees to create or control".
Eric ran that back twice.
"You're telling me that somewhere out here, there's a guy with a lanyard and a coffee mug whose entire job is hunting people in my world".
"Yes".
"Does he have a performance review?"
"He has a quota", said the entity, and moved on.
The gear came next. Owners in the physical world strap in, and their real movements and facial expressions are copied onto their avatar. They watch on a screen or through headgear. Mic, controller buttons, gloves — and the gloves were the part the entity clearly liked, because it slowed down.
The gloves let an owner "feel" what the avatar touches: vibration and pressure applied to precise areas of the hand, matched to contact in the world. If the avatar's hand meets something solid and its fingers can't pass through, the gloves produce the corresponding sensation — even when the owner's real hand keeps moving through empty air where the avatar would otherwise phase through the object. Firm contact means real pressure on a real hand. And if something in there smacks the avatar's hand, the glove delivers the jolt.
Then the time zones. The simulation contains regions, rooms, and whole universes running at different rates. Enter one, and your avatar automatically syncs to its speed. Some zones are locked to real-Earth time. Every copied universe runs on real-Earth sync; original universes run independently, as separate units. Gear users can only reach the real-Earth-synced ones. Other avatars can travel anywhere a connection exists.
"And when an employee-controlled avatar kills a simulated existence, that victim is automatically teleported to a dedicated afterlife-universe, at a random location, which has its own various exits back out into other universes. Gear users cannot access that one at all. Employee avatars override the local universe's death system, so the aforementioned dedicated afterlife-universe system is what happens instead.
"Of course they can't", Eric thought.
"To finally answer your question about control: your movements in there will be almost identical to how you moved in dreams. Your ability to observe imagery will be almost identical to how you observed imagery in dreams. Except all of it stays bound to your avatar's actual motion, and your avatar's motion stays bound to the laws of whatever universe it's standing in. You will control it as if it's your own body. You will move and act through it. And your speech will only be transmitted while your avatar's lips are moving in a way that looks like speech".
"So no ventriloquism".
"No ventriloquism".
"Damn".
"Our computers will send impulses to your somatosensory cortex identical to real touch signals. Phantom sensation for contact, collision, and the rest. Your avatar cannot pass through solid objects unless that universe's parameters permit it". A pause, and for the first time the entity sounded like it was saying something it believed rather than something it had memorized. "Part of our goal is for it to become indistinguishable from reality. The other part is that it doesn't have to be".

Eric lay there and felt the shape of something finally clicking into place — something that had been bothering him for hours.
"That's why I never see it coming", he thought. "Your voice. I kept thinking I was saying things without having thought about saying them. It never occurred to me that someone was talking to me until I was already halfway through hearing it. You make my mental voice speak to me, except I never spent any time figuring out how to word it. There's no run-up. So I never see it coming unless I'm already waiting for a reply, or unless I'm bracing for the fact that it can happen again at any time without warning".
"Yes". Something almost like approval. "The mind cannot produce sound. But I can use your mental voice to do a non-audio imitation of the sound of anything or anyone, and you'll observe that imitation through your own imagination. Which is why I deliberately use an imitation of a very noticeably different voice than yours. If I used yours, you would eventually stop being able to tell which thoughts were which, and people who reach that point tend to stop being useful to talk to".
"That's considerate".
"It's efficient. Of every method I have for using your imagination to communicate, this one is the fastest and, in my opinion, the most comfortable". A beat. "You would not enjoy the second-fastest".
Eric decided not to ask.
"One last item of housekeeping", the entity said. "An avatar will notify you when it's 9:00 p.m. real-Earth time, every day. When you want to rest, you'll hold your avatar's pinky to its bellybutton for sixty seconds".
"...I'm sorry, what?"
