Not many centuries after the creation left his creations, the Invaders continued to make alterations and more claims of the vast different parts of his creations.
However there were only two invading bodies that did this and they were, Haklar and Jumari. Though these two barely had any relations to the creator of any sort, their powers and abilities made up for the lack of omniscience that He had. Not in a complete way that they had his abilities or could perhaps mimic them. But in ways that enabled to divide and conquer the ever vastly expanding universe that He created. And as they took, they grew stronger. So much so that within just after 20 millennium, they were able to become akin to deities of the sort. And with that they settled down and continued to reshape, build and create worlds from the own akin to what they'd call their own pieces of work. Knowing deep within that if He had not left and and had not left at least just this bit of all his perfection lying around then they truly would have never obtained the opportunity to come close to what humans refer to as 'Godhood'.
And soon after the two who were once greatly against each other in thier struggle for power and territory, soon came together in a meeting. They told themselves that they would host this meeting with themselves once after every Verseshift.
This then therefore resulted in many conclusions and actions that were further made as time grew with them. They realised that there were many holes in what they had claimed to they had thought were complete masterpieces. Creations with astonishing mends and and refinements akin to His. But as they had these meeting they came to numerous conclusions about their 'works' and started to adjust align them even more in accordance to their critique.
One of them was the constant cracks that appeared in space. Signs that their adjustments were not enough to replace He had taken with Him. Another being the rapid birth of what they called impurities in their territories which were of course no harm to them but would of course would not be of any kind of disturbance to them but would be to their 'akinly' perfect creations that they saw had at least the same footing as His creations. These were things like dwarf planets which some of these impurities ate for the sake of multiplication and survival. Others were what would be referred to as their co-creations. Beings that were meant to be even more perfect than His own at least they were to them. Another problem was the same that He had been dealing with and maybe still was as he tried to fix the parts of his creations that were tainted by all-versal entity know as Corruption. The one who brought sin and corruption himself into the creators creations. And the even greater issue was even after He left, the damned pest never left existence alone. Not even for a fraction of nothingness. He stayed because... this creation was originally His. And so his role was to taint it completely no matter who stepped in to stop him of claim what belonged to his long found Nemesis whose name we all know as Yaweh in thus universe.
Another issue was slumped growth of their territories. Not in terms if magnitude but in terms of their 'co-creations'. And this upset them. As they watched the creations of Yaweh continued to evolve and grow. Both mentally and physically. So this stack of problems just truly weighed on their prides and so they lit it be. But that did not mean that they be as shallow as to let this continue, no, for beings like them who had achieved so much in such little time. They thought to themselves that they would truly prosper once again, right? They didn't know. For their soreness only came from the result of their works not from the shire will of their minds and spirits. No. That power only belonged to Him, to Yaweh. And He had left His ruined creations. Which spiked the greed and alertness of these two. They wanted to know why at a certain point why He left? But they had no time as for their sharpened greeds and keen observations made them less prone to this thought and so they carried out in their actions at lear knowing that... He wasn't here to interfere anymore.
And as we get to how they solved these issues we see that for the cracks they deployed special creations of their own called Nemorphs that explode and jam the cracks wither condensed energies in their bodies that collects over every half a millennium around the same time when the cracks occur. For the impurities, they wanted to use their co-creations to solve the problem. But all in all end up having to use even His creations to help solve the problem. And all the others. And thus was done through things that led obe from one even to the other which we led to an event that truly meant that tampered with His creations. This event known the Grwat Reconstruction.
