Tide plays with some putty.

'They really stand no chance in a one on one battle' thought Tide as he observed the greater Tzeentch demon held in his mental grip.

'Or its just that they have no defense against Neural Physics' he queried to no one.

the Emperor gives him a nod.

He turned to the side, in as much one can turn in this realm, and placed the putty it with the rest of the Tzeentch putty.
Comparing the much larger Tzeentch putty with the putty from the other gods he figured there were about even with what he had just put down. Though the pile of putty drawn directly from the warp storm above the planet was greater then the rest by a large margin. A margin that suddenly grew a small amount as a bad wave from the storm hit.
the planet.

" I should really use all this for something before it takes up to much room or gains a mind..." he spoke out loud to, again, nobody.
The Emperor takes aim.
That's when a Figuratively bolt from the heavens shot down and smote him right then and there. The God Emperor seeing this shakes from the laughter he holds down.
Shaking off the smote he grabs all 5 piles and and all but smooshes them together. Looking around he tentatively reaches out and grabs a golden beam that shins from the warp. Somehow. in the middle of a warpstorm. The Emperor rises his hands in victory.
He then proceeds to add the beam to the putty and mixes it all over again. Once it is perfectly mixed he molds it into a rough shape of what he is looking for. Then using his will in different shapes and using the knowledge from the several million people he proceeds to shape it with greater detail.

Time in the warp depends on the narrative and as such what seemed like a personal subjective time of several months that in the material world passed so fast that time might as well have gone backward for all the difference it would make. Looking over his creation Tide nods to himself and reaching up grabs as much warp stuff as he can defend and pulls it to the model. As the model drinks in the warp stuff Tide grabs more and more. never noticing the solid golden beam the entered.
As he is doing this he pulls memories from all the people and builds the greatest and most well adjusted person to ever walk the cosmos.

An FPS Player. The Best Team FPS Player to ever exist.

With the demons kept out and the warp storm still being eaten Tide proceeds to make copies by the thousands. Once the system is self sufficient he then pulls slightly from the warp to build the best FPS experience.

Once that is built, again in time that was no time at all, he attaches it to the view of his altered and new minions. After all no reason not to have fun just because the world is a terrible.

With the two new systems in place he now has a defense that will first both protect him from the warp and something that will also harvest the warp so that is one less thing he has to pay attention to. With the system attached he can now pilot the altered or minion and live out a game experience. After all Why shouldn't he have fun. He is a pers... well was a person. IS? Was? Ehhh... He needs to have fun too.
The Emperor leaps with joy at having someone to game with.
Tide wills up the best gamer chair and leans back to have the best gaming experience to have ever happen. He reaches out and the emperor hands him his favorite drink. Startled but not surprised Tide takes it, salutes Big E and with another tentacle hands BIG E another controller.

They both lean back and proceed to lean back and have a great guys night out.

And thus the universe was saved...
in the most lazy way imaged.

TDLR: I had fun writing this out.
