Reality Marble

**Reality Marble** (固有結界(リアリティ・マーブル), *Riariti Māburu*) is the pinnacle of all Barrier Magic that allows the caster to materialize and project their inner world onto reality.

## Summary

The concept of a Reality Marble is one that centers around the materialization and projection of one's inner world onto reality following the **World Egg** (世界卵, *Sekai Tamago*).

Only magic practitioners who have dedicated their entire life to perfect their Barrier Magic, and as such, Reality Marbles represent the pinnacle of all Bounded Fields where the boundary line becomes the space itself.

## Characteristics

The created worlds that are Reality Marbles are completely cut off from normal reality, projecting their internal landscape and sealing off the regular principles of the world. Following the World Egg Theory, the actualization of a Reality Marble is the result of switching the [Self] and the [World] while keeping the boundary the same.

The size of the [Self] and the [World] is switched, enclosing the World in a small container while the Self is expanded, and the contained world is the World Egg and the name of the theory. They will encase anyone within range, causing them to disappear from view. Magic practitioners are still able to feel the presence of the Bounded Field, and while they cannot be directly affected from the outside, a large burst of magical energy may be able to disrupt them.

The [World] constantly attempts to crush the unnatural Bounded Fields as they are not created by spiritual beings, meaning that it costs a great deal of magical energy to construct one and keep it stabilized, as even a God-Class caster cannot maintain a Reality Marble for more than a single night. This generally only allows them to be used for a few minutes, but given their powerful nature, that is likely enough time to properly utilize them. Each [World] has its own set of patterns and rules, which can be said to be an invasion of reality by the diagram inscribed on the soul, and as it is just one aspect put into form, the user cannot add their own will into the form of the barrier.

The magic practitioner can also make use of certain aspects of their Reality Marbles without activating them, and some can be activated inside the body of the caster to avoid the corrective impulses of the [World]. When two Reality Marbles are deployed, the one with the higher output (magic foundation, magical energy) would be deployed. If both parties are equal in power and successfully deploy their Reality Marble, they would enter a state of two worlds in conflict. Reality Marbles do not move from the place they were deployed, the caster would have to decide whether to draw the enemy into their own world, invade their opponent's world to crush them, or wait for both to run out of time and go back to fighting on neutral grounds.

It is the closest to Enochian Magick, a taboo among taboos, mystery among mysteries and one of the pinnacles for non-celestial magic practitioners, so researches on it have been banned by the Abrahamic Institutions. That said, Reality Marbles are also still considered mortal magic, a series of taken tricks to deceive the world, taken to its logical extreme.

However, obtaining a Reality Marble is not something every magic practitioner can achieve through research. Even Odin, a God of Magic whose arcane powers are far above all modern magic practitioners, can only construct "another world" of the same scale with enough time and expenses instead of a Reality Marble. While obtaining a Reality Marble is very hard, a user can pass his Reality Marble down in some way once they get it.
