Side story

Terra, the Hall of Leng, the favorite place of the Emperor...

Ever since he transmigrated he didn't know what to do with his almost great amount of free time. With the help of the mega intelligence he basically turned the Whole Imperium upside down. He still has jobs to do such as approving things here and there but generally he can finish it all quite quickly. He didn't bothered himself with trivial administrative matters and only acts when the matter regards the future of the Imperium, it's his son, Roboute's job to handle those trivial matters.

So here he is strolling casually on the Hall of Leng followed by custodians. He remembered that this place is the past time of him before. He's holding a plate of simple cookies. He didn't need to sleep or eat but he still casually did so because why not enjoy simple things.

"Wait here, don't let anyone inside." he ordered to the custodians which immediately stood guard at the entrance of the hall as he finished the cookies in the plate and have a nearby custodian hold it.

He entered the hall and played with pretty much everything there.

"Hmmm, based on my memories, this hall is where past and future co-mingled and is an anomaly in the immaterium." he said as he tried to measure the angle of space and time and he concluded that it still works normally just like in his memories.

He already considered the memories of the former owner of this body and soul as his years ago.

In this past decade, the memories of his past life has long since steadily vanished from his mind without him noticing due to the body and soul of the God-Emperor overpowering his consciousness destroying his memories in the process. As the memories from the emperor entered his mind his memories of past is destroyed by the body detecting it as a foreign object. Like on how will the body act when a foreign virus enters it. It will do everything to expel and destroy the body. This same thing is happening with the God-Emperor and he doesn't notice it due to it feeling totally normal for him.

He is becoming slowly the actual God-Emperor himself except for the influenced attitude on some matters due to experiences. He may have his memories about his old world forgotten but his experiences there are deeply embedded in his very consciousness that it still influences on how he act on certain things today.

"Interesting, even without the supposed presence of the immaterium it still works perfectly fine." said the Emperor as he started to experiment with the things inside the hall.

The curiosity part of the God-Emperor has shown once again as he started to experiment on things trying to uncover the mysteries surrounding the souce of their psychic power.

His assimilation to the soul and body of the God-Emperor is almost complete. Nothing can stop this matter from happening not even him even if he wills it. He'll be a reforged version of the Emperor as his past life experiences will shape and improve the Emperor on some aspects.

Another dawn will descend on the Imperium and this dawn will surely be a good one.
