I had many of the questions I had been trying to find answer to answered.
Just like I suspected, the Nothingness was not a sentient being and was driven by something similar to instinct or a very basic program.
It was everything that wasn't and for the longest time was the only thing, if you could even call it that, until a miracle happened and the first reality was accidentally formed.
This world was the first thing to exist and the birthplace of Azathoth. The Nothingness had no mind of its own and with that, it didn't have the required imagination or fantasy to form new worlds, instead, it decided to use the imagination of other beings.
That's how the next few realities were formed but soon a problem arose, the Nothingness was too corrosive to the newly forming existence, and the few living beings bonded together to stop its destructive nature.
They could do nothing to stop it and many of them fell, but they had plans. Since they couldn't stop the corrosion, they just recreated what had been destroyed but since they lacked strength, they could only slow it down.
They crafted together a plan to increase their power by spreading stories with ways to get stronger, resulting in the first cultivation and fantasy worlds but another problem soon arose. The more beings existed the more beings needed to imagine the same thing, it was easy when there were just a few dozen beings but once the number passed the billions, more and more people needed to believe.
In the end, only Azathoth was able to grow strong enough to hold the Nothingness back and even slightly push it back as new realities were being formed but there were some things he overlooked.
The Nothingness was infinite, it could only be used to this extent by someone who existed, and the Nothingness present even in existence. Nothingness was everything that wasn't and Existence everything that was but even Existence had things that weren't, for example, there was no air underwater and vice versa, he could just stop its destructive properties, not its nature.
At some point, there were so many beings that a unified imagination was impossible and Azathoth's growth completely stopped. From then on realities could be categorized in the following categories, artificially created, created by imagination, and the rarest form, naturally formed.
Of course, not every imagination world originated from the same place where these stories came from, sometimes the Nothingness would send dreams of other worlds across Existence as a form of gratitude but since it didn't understand the concept of individuality and just saw life as one being, the gratitude often ended up in the minds of persons that had nothing to do with the formation of other worlds.
The next thing I learned was that I was not the only one with the divinity of Nothingness but no one was as unique as me. There were very few beings who could use a small portion of the Nothingness but in the end, their status as a being that existed prevented them from using any more than that.
I didn't exist so even if I had just awakened my divinity, I was already more proficient and powerful than them and I would continue to grow. But all that mattered little to me, I was more interested in the benefits I had as a non-existing being.
While these beings with Nothingness divinity could only use some of its destructive properties, I was more interested in its creation abilities because unlike them, I actually had some say in the Nothingness.
I was still not the very concept of Nothingness as I had hoped but I would be by the end of my plan. I could slightly guide the creation of things as long as the idea already existed and was known to enough beings.
The idea of Essences was rather widespread but their power was too great compared to how few people knew of them, with one exception. If you were to ask around which Essence they would choose, nine out of ten would say the Essence of Blank, which was also my only hope of surpassing the barrier between me and the Nothingness and becoming one with it.
The idea of the Essence of Blank was already solid enough, it just needed enough power to form. I would use my pathetic control of Nothingness to guide my energy to this idea and let it form for me, there was only one problem.
The energy needed for this stunt was billions of times more than what I had and that was very underestimated. I would have to spend a long time here to create this thing, or none at all, since I had a little control over the Nothingness I could just return to the exact moment when I came here.
The only question that was left unanswered was how I became what I now was.

A/N- Makes sense, right? Finally an explanation as to why there a so many fictional realities besides the stupid infinite Omniverse theory.
