The entrance to a Plane Gate?
Locke carefully observed the spatial vortex. It was indeed not a dimensional gate, nor was it a gate leading to a demiplane.
Although Locke had never visited another plane, he knew from various journals and documents that a First-Ring Wizard did not possess the ability to cross the Great Void alone and escape the protection of the World Principle.
Therefore, during the First-Ring Stage, if a wizard truly wanted to explore other planes, they generally would not sit aboard a Void Battleship and invade from the front. Instead, they would excavate and search for planes that had some kind of [coupling relationship] with the Wizarding World.
The so-called coupling referred to two objects forming a connection for some reason despite not being in contact.
In this world, countless planes were scattered throughout the Great Void.
The spatial distances within the Great Void were incomprehensibly vast. The normal distance between two planes was extraordinarily far. Even within this stellar system, no one knew how long it would take to travel to another plane.
But even so, the heavens had still given the Wizarding World a way to make contact with other planes before mastering long-distance void navigation.
That was Elemental Particle Entanglement!
In other words, some of the elements in the Wizarding World had become coupled with the elemental particles of a distant plane, separated by an unknown number of light-years. This gave rise to the special phenomenon known as a Plane Gate.
Through this Plane Gate, one could enter another plane.
It was like passing through a black hole into another world, traversing an incredibly distant stretch of the void.
The Dragonbone Plane and the Tewell Plane controlled by the Land of Six Towers had both developed Elemental Particle Entanglement with the Wizarding World,
