I hum as I drift lazily through the void between multiverses, absently, when I notice a stray universe out here in the Outside, so I jump over to it with a bit of will.
As I arrive I gently grab the universe and inspect it to see what it's origin is and if I can figure out where it belongs, when I bring the tiny speck sizes ball up to my eye I see that it it is the Warhammer universe and the reason it is so far from its multiverse is because in this universe the tyranids had won completely and no other faction existed with the last being chaos who had staved with the lack of new sentient species to prey on.
"Welp, don't think the cluster will accept a dead story" See, when a universe like the Warhammer one spawns a multiverse, the World will start pruning those that no longer have a story to tell, meaning if one faction wins completely, the World dumps it into this space, but that only happens very rarely.
I hold the universe to my chest and push it into my personal cluster before jumping there myself and arriving in the massive library I call home.
I grin as I watch the infinite space expand with all of the knowledge I have gathered as I lived, and even then, it still only holds a fraction of what I truly know.
I walk towards my living area in this library, and while I do so, I run my fingers across the spines of the books I pass before grabbing the new addition.
"Oh, this place has finally transcribed the Necronomicon," I say with glee as I open the Book of the Dead and peruse its pages while batting away the Outer Gods' attempts to enter my mind with the equivalent of a smack on the hand.
For a while, I just reread the book to see if this place had properly transcribed it while fixing any mistakes I found.
"Well, you were close, old friend", I say while giving the bookcase a pat and placing the book back on its shelves, while the library sends me the equivalent of a small puppy barking happily.
"Best to not leave that universe to itself for too long, it might dissipate" I jump over to the trophy room and make my way past all the dead god's weapons I had collected and the heads of the elder god that had thought it wise to prey on the being who awakened Azathoth from its slumber without collapsing the omniverse.
"Ah, here we are, the only previously empty room in my home" Nestled between the head of the creeping chaos and the spear of heaven, I stand before a large door decorated with all manner of shifting murals.
I push the doors open and make my way to the lone pedestal in the room and the tiny speck apon it's surface.
"Well, should probably fix the tyranids problem" With a flick of my wrist, I conjure a mirror to view the insides of the universe and start rewinding time.
"Ah, too far", I mumble as I see the war in heaven before I change the time back to where I wished to go.
"The unification wars", I say (mainly so the library's developing mind could listen to me), when I reach the perfect moment in time for my own entrance, I start to design an avatar for my time in this universe, when I suddenly remember my favourite god I had ever met.
"Yes, this will do", I say as the small child-like body forms with playing card symbolism, each eye and the heart symbol under the right one.
When I was happy that the body had formed, as I remembered the god to look like, I infused it with my essence before placing it in the universe on a random planet.
Line break
"Wow, that's a head trip", I mumble as I shake my head to clear it of the fuzziness that comes with the possession of an avatar.
I look around at the area where I had arrived and all around me I see nothing but scrap and junk as high as the (mortal) eye can see.
"Guess I landed on a junkyard planet", I shrug, and with a bit of will, I disassemble the planet beneath me before reassembling it as disboard, along with completely changing history to make it so that this planet has always been like this and so far hasn't been found by any race, including the old ones.
I snap my fingers, and all across my new planet, the races of Disboard start waking up with memories of life on this planet.
Satisfied that I had successfully recreated Tet's home I decided to have a look around in the warp to see if my planet would have any troubles from it.
Using a bit of space manipulation, I create a portal to the warp and drift lazily through to the other side, and what I see is both unsurprising and annoying.
"God, now I see why revelations call them a cancer on all sentient life" I use a small flash of pure holy magic and clear the area that surrounds disboard of all demons and those like it before claiming the space as MINE and enforcing the tenets of disboard in my claimed space.
Deciding to get the probing of the chaos gods over and done with now, I set my stance and created a gargantuan bow made entirely of holy flames I had learnt from YHWH and three equally large copies of my space rules transcribed into solid durasteel arrows.
I pull the holy fire bowstring back and, with a quick prayer to Artemis, who may not have existed before I made the prayer, I let the string go. The arrows blasted off with enough force for the people all across realspace to feel it.
I didn't bother watching to see if those arrows hit their intended targets and instead teleported myself into the Garden of Nurgle.
