The discovery of teleportation came from the creation of the space rune. Honestly, I expected it would take much longer to bind such an abstract concept to a rune, as it did with the other elements. But, surprisingly, it proved simple.
All I needed to do was convey the idea of distance.
I still don't fully understand why it worked so well. Perhaps it's a concept already internalized by the people of this world—something so fundamental that magic itself responds to it naturally. Or perhaps it's related to the connection I experienced that day with the earth… that moment remains poorly understood. I don't know exactly what happened back then—only that, since then, certain things feel… more accessible.
For now, our limitation in teleportation lies in coordinates.
The method we developed relies on an anchor point—a fixed location in space defined beforehand as the destination. It isn't elegant, nor particularly versatile, but it is stable. Given our current circumstances, that alone is enough to serve as a safeguard.
Even so, the creation of the space rune led to another possibility.
The idea of spatial expansion.
If it is possible to manipulate the distance between two points, then, in theory, it should also be possible to alter the internal relationship of a space. To expand it beyond what is externally visible. A space larger on the inside than on the outside.
The concept itself is not new to me. I have encountered similar ideas before—structures where the interior does not match the exterior. But applying that here… is an entirely different matter.
Teleportation deals with displacement. It shortens the distance between two points, even if we do not fully understand the mechanism behind it. For the most part, it was an accidental discovery.
But expansion is different.
Expansion requires control.
I cannot rely on trial and error for something like this.
If there is a failure—even a small one—the consequences could be catastrophic. A flaw in the structure could create instability. And instability, when it comes to space, is not something I can simply fix afterward.
In the worst-case scenario… a collapse.
And I have no idea what that would truly mean in this world.
But I have a suspicion.
Nothing inside that space would survive.
To achieve this goal, I will need to delve much deeper into theoretical research. Unlike teleportation, I cannot afford to proceed through experimentation alone. Only when I have a sufficiently solid model—something I can explain, predict, and reproduce—will I consider moving on to practical application.
For now, I can formulate a few hypotheses.
Hypothesis 1: Spatial expansion as manipulation of distance.
The most direct approach is to treat space as a relationship between points. If I can shorten the distance between two distinct locations through teleportation, then, in theory, I should also be able to do the opposite in a controlled context.
In this case, I would be working with two overlapping spatial "layers"—two areas occupying the same external point, but with an internal relationship that can be altered. Expanding space would mean increasing the internal distance between these layers, without changing their external position.
In practical terms, it would be like stretching the interior without moving the boundaries.
If this hypothesis is correct, then teleportation already provides a foundation. It demonstrates that distance is not fixed—it can be manipulated. The problem is that, in teleportation, this manipulation is momentary and directed between two defined points. Here, I would need to sustain that alteration in a stable and continuous manner.
The challenge, therefore, is not just altering distance… but maintaining that alteration without the space attempting to "correct" the distortion.
Hypothesis 2: Expansion as the creation of an anchored space.
Perhaps I am approaching the problem incorrectly.
Instead of expanding an existing space, it may be more viable to create a new one—a kind of separate "pocket"—and anchor it to a specific point in the physical world.
In this model, the interior would not be a distortion of the original space, but an independent space connected through a controlled interface. The visible entrance would merely be an access point, while the actual volume would exist "outside" the conventional structure of the world.
This would explain how a space can be larger on the inside without directly violating external proportions: it is not being expanded… it is being connected.
If this is the case, then the space rune would not only manipulate distances, but also relationships between planes or distinct regions of reality.
The concept of an anchor, which we already use in teleportation, would become even more critical here—not just as a destination, but as a point of stability. Something that prevents this space from drifting, collapsing, or worse, becoming completely disconnected.
This approach appears safer in theory… but also more complex.
Creating a space is fundamentally different from modifying an existing one.
And, more importantly, it requires a much deeper understanding of what "space" actually is in this world.
For now, both hypotheses remain incomplete.
But they are a beginning.
And, considering what is at stake… a solid beginning is all I can afford.
Author's Note:
Geralt is still far from testing any of these theories in practice… but you aren't.
I'd like to hear your thoughts:
Which hypothesis seems more plausible?
1 — Manipulation of distanceSpace is "stretched" internally. Expansion occurs by increasing the distance between overlapping layers while keeping the exterior unchanged.
2 — Anchored spaceA new space is created and connected to the world. The interior is not expanded—it exists separately, accessed through a fixed point.
If you want to go further:Is there a third possibility that Geralt hasn't considered yet?
