Edward did not understand, but he was utterly stunned-using an entire world as a Uniqueness? That idea was fucking brilliant!
But on closer thought, it seemed quite reasonable. After all, his authority had originated in the Harry Potter World, and this world was also the ultimate embodiment of the power of "I reckon." Nothing could have been more fitting as a symbol of that authority.
"But achieving all of this requires 'imagination.'"
He blinked. "So, where are you going to get that much imagination?"
Edward froze, then said instinctively, "Didn't you just say that in the Harry Potter World, I could freely..."
"Exactly! But that's only in the Harry Potter World. Here, even before advancing to Sequence 0, you're an invincible Creator. Even Outer Deities would be subject to your restrictions if they came in."
He tipped his head back slightly and chuckled. "But what about outside?"
"You haven't forgotten, have you? However close to reality the Harry Potter World might be, it's still a Book World I imagined and constructed. Fundamentally, it's no different from the world in Groselle's Travels."
"So its level of existence is lower than that of the Lord of Mysteries World. That's why magic from here becomes so much less effective against Beyonders. Even an outstanding wizard like Dumbledore might not be able to defeat most Sequence 5s, or even Sequence 6s, with everything he's got."
"This imbalance in levels of existence is caused by a difference in dimensions. If the Lord of Mysteries World outside is three-dimensional, then this place is two-dimensional. One dimension apart, a world of difference. Just like Sun Wukong in Dragon Ball-even if his hair turned rainbow-colored, he couldn't do the slightest harm to the person reading the book."
His words left Edward deep in thought for a long time.
