Somewhere far away, in the midst of seamlessly vast Universe, A breathtaking scene unfolded itself. A neutron star was surrounded by ginourmous multiple mechanical rings, which were extracting it's energy. Above it was a giant spaceship, 200 times larger than the star. In a large chamber surrounded by intricate machines, a round sphere of silver was floating, surrounding it were 3 holograms of spheres of similar build and colour. For the moment everything was still, eventually (Any updates on the "key"?), one of the holograms spoke without moving, as it had it's vocal organ inside it's spherical body. (Our side scanned through 98825 universe, no clue found)
Another sphere hologram voiced. (Our side has 10% energy left for worm holes' usage, we have already explored our side of universes') the third one spoke. Seeing this, the first one retorted the second (Umbar, you should have used your wormholes to accelerate the search faster, what if the "key" is destroyed or lost among high gravity bodies, or maybe stuck in a black hole?). Seeing this, the actual sphere watching the 3 holograms hummed ( It's okay Zzar, firstly this entire idea of searching the "key" is farce, they shouldn't have lost them in first place, those Gonarks, now they are bossing us around despite being a type-3 civilization themselves, what can us type-2 ones even do, if not just continue this wasted search). Zzar replied (Nonetheless, let's continue the search, if any of your soldiers find something related to it, don't forget to inform us. That "key" contains access to vast reserves of 8th- dimensional multiverses' energy. Neither we nor those type-3 Gonarks can do anything about it, they must be planning to offer it as tribute to those 4th dimensional type-4 civilizations, maybe even 5). Hearing this, other 2 holograms and the sphere laughed mechanically. (Hum..Hum..Hum..Hum.. you sure jest Zzar, I don't think even Gonarks have connections with them, anyways, I going back to work) saying this, Umbar disconnected, as well as others too.
Eventually, the sphere returned to manage the energy collection of the star, when a call drew his attention. (What is it?) Speaker stuttered as he spoke(Bo..Boss, we saw a light from one of the outer galaxy in our universe, i..it has the same wavelength as the "key"!!!!!). Hearing this, the sphere froze for a moment. It got it!! Not just the clue, but the location of the key!!!!! While everyone else was scrambling through other universes', it might take such an unimaginable power all for itself!! While it was lost in such thoughts, the entire universe in which the sphere was located vanished along with it and it's subordinates, as if it never existed.
At the same moment when the entire universe ceased to exist, the "key" hummed happily, free energy was always good energy. It wasn't a sentient being, but after Sanu perished, it carried his memories and soul in itself, while it was synchronising with Sanu, it felt immense threat to it's existence, it first checked the conditions of humanity, since Sanu was one. After seeing that humans had ceased to exist long ago and the planet was basically a ball of fire, it simply absorbed the universe in itself, which wasn't even a drop in it vast reserves of energy.
While it completed the synchronisation, it peeked into the memories of Sanu, the thing which intrigued it was Sanu's wish, and after it saw the "system" in the novels Sanu read, as if grasping the basic framework of system by reading novels itself, it completely modified to turn into a system, and used the energy absorbed from this Universe to warp itself and it's host to a certain planet in a young universe, to the type of world Sanu always dreamt of living in.
