The construction of the Flame Origin Camp did not involve Liszt, as he and Ach spent the whole day studying the Whirlpool Entrance; when no traversal occurred, everything appeared normal.
Even when Ach unleashed Super Magic to communicate with the Magic Web, while the Magic Web appeared, there was no sight of the wormhole space that would tear through the Magic Web. Ach gave a relatively reasonable explanation for this: the Magic Web should not be deduced by common sense and there is no such thing as physical distance.
Liszt summarized it.
The world he was in could be described in three dimensions, so the Magic Web was an existence that transcended those dimensions.
