The internal worlds shared the same rules, only divided into five regions: East, South, West, North, and Central.
At most, the five regions were separated by a space wall, but that was it, no more barriers.
In the past, inter-domain travel merely required passing through this spatial wall to enter other domains.
However, at the end of the Fourth Epoch, during the War of the Worlds, Shen Hong collided with two other ultra-large Vast Thousand Worlds Groups.

This led to the Fifth Era, spreading the End of Dharma Era throughout the Epoch, which, even now, despite many places having their void cracks repaired, had not fully recovered.
