Space was extremely huge and vast.
This was even more so when one looked at an entire galaxy that housed an uncountable number of planets and creatures, and it was even vaster if one took into account the unknown that lied outside of a galaxy!
Yet there existed a few specific beings that could effectively achieve a high enough level as they actually changed how vast things seemed to their perception, rising to such extreme lengths of power that even the vast distances of a Galaxy did not seem as vast as they were before.
This was the case with Noah after he achieved the level of a Grand Controller, the type of movements he could do within the Novus Galaxy expanding greatly to the point that he could not even compare it to his past self!
An example was how he and Aldrich had gone from the Central Realm and into the Letalis Expanse, and then just a few minutes later reached the bounds of the Novus Galaxy as the events that had already occurred took place.
