**Author's Note:**
I saw that many readers didn't understand the protagonist's situation in the previous chapter, that's normal.
I reread, and I observed that it's not easy to understand with ordinary readers' computer information (basic knowledge about 40k and Leylin Farlier's universe).
Sorry, I should have lengthened the chapter and taken time to explain (at the risk of too long a monologue... and I've suffered too many complaints in comments about that).
Well, I'm going to summarize it here if the previous chapter or even this one wasn't enough to enlighten you about the situation.
The protagonist used a divine rank spell to reincarnate in the 40k universe, as a native (yes, a native, because the world itself recognizes him as a guy from there).
It's different from the Konosuba case (he literally went to Konosuba entirely and as a foreigner).
Currently, his body sleeps but he controls his Warhammer 40k version like when you play a video game (he risks nothing except the clone's destruction).
He could have sent a proxy clone, but the laws in the 40k universe are extremely severe toward supernatural entities, a bit like in Type Moon (he would risk sending his clone directly into the Immaterium, so to Khorne or another Chaos god lol).
Because the Immaterium's demons are entities born from people's beliefs and emotions from the material world.
Thus, Sanguinius (an angel or supernatural creature) isn't really in his element in such a world (the material world will just throw him in the Warp, because he's a foreigner and a different life form from a simple Xeno or human).
Little bonus info: I'm posting this here, because there are too many readers who don't read the author's thoughts... and they're annoying talking about stuff already explained or already.
….
[Reincarnation in an alternate world, Rank 7 Spell.
Ability to divide the true soul from the main body and project it into another world for reincarnation.
The main body will have absolute control over the true soul clone and will synchronize perfectly with the frequency of the world's origin force, thus receiving the treatment of a native.]
'I... I already know all that... but, keep talking.'
After losing consciousness, Sanguinius's consciousness was completely concentrated on controlling the secondary soul.
The situation was different from proxy magic.
If the first created a perfectly autonomous clone, but subject to the main body's interest.
The rank 7 magic allowed creating a pure native in another world, who is controlled and guided by the original.
That's why Sanguinius had the necessary confidence to accept sleep.
'I... I mustn't sleep... or...'
He was currently being tossed and torn in all directions by an energy storm.
If this storm came from the Warp, then he would be panicking.
But that wasn't the case.
The energy surrounding him is potentially older than the Immaterium itself.
It was the origin energy or pure energy of a world.
A power at the origin of arcane civilization's destruction, which every world possesses.
This energy attacks... no, it cleanses Sanguinius's soul.
This was a form of baptism or brainwashing.
The world will's purpose is to make Sanguinius a pure native of the Warhammer 40k universe.
So he had to be "reborn" to accept the natural laws of this universe and abandon the ancient logic known to him.
Of course, he didn't agree.
That's why he reviewed the data about himself thanks to the AI chip.
Finally, the translucent and protective energy of the rank 7 spell disappeared under the relentless assault of the world force.
Void.
Infinite.
Terrifying.
Sanguinius was no longer sleepy, but he was facing something immense and ancient.
He couldn't describe it with words, but it clearly escaped logic.
The world power brutally penetrated the soul, which subsequently wandered in the energy storm.
He was completely washed of everything that wasn't sufficiently linked to his very essence.
The world energy began to restructure everything, but was stopped by an unknown force the moment it touched his consciousness.
'...the spell?!'
That was the only explanation behind the sudden stop of this superior entity.
While he believed the cleansing was over...
Small unknown brilliant fragments began to cluster toward him.
No, this had nothing to do with the world will.
[Alert!!!]
[Unknown spiritual energy!!]
[It is recommended that the host move away]
Sanguinius wanted to insult the AI chip for its useless advice.
Normally, he should have lost his skills like Divination because of the world power.
But... there was an anomaly.
Something in the spiritual energy reinforced these skills, which were disappearing one after another in the infinite void.
Several flashes of images were seen by Sanguinius, as he was dragged by the lights to a specific place.
As he lost 'consciousness' again.
Sanguinius saw an image that pushed him into infinite sadness and bottomless anger against himself.
'H...Horus'
The arch-traitor taking his life breath.
At that moment, he was unable to listen to the group chat alerts about his new updated username.
...
A dead world.
That's how any normal human from 21st century Earth would describe Baal or its moons.
Yet, it hasn't always been this way.
There was a time when a technologically advanced civilization lived on these lands, but that dates back to a distant era.
Today, few natives are aware of this era and the secrets behind its end.
There was now, on the moon Baal Secundus, an event that would shake this world and the foundations of the Imperium.
In a tent built with various materials gathered from the desert, there was a sweating woman.
She wore a face in distress because of the pain related to childbirth, but also to the environment unsuitable for it.
While she was in full labor due to the baby,
one woman was mumbling prayers in a strange language, and another was giving her instructions.
After a long moment, which seemed like hours to the woman...
Crying sounds echoed.
The tribal midwife, or Sang'dula, grabbed the newborn child, who was still crying.
At first, the wise woman was relieved.
But her expression quickly changed.
"Skar'Nathi?!" The woman immediately identified the mutation, using a term specific to the moon's tribes.
If the child had been born in a tribe that hated mutants, he would have definitely been thrown into the radiation-polluted desert or simply executed.
But fate favored him.
The elderly woman next to the wise woman took him from her arms with a certain reverence.
"...You are a Skar'Nathi, our tribe has been favored by the Winged Father."
Without giving the baby to the mother, the woman began to put on the child's skin a mixture of radioactive desert sand, bones of unknown mutant creature and other plants irradiated by radiation.
The child manifested strong protest, but the old woman simply ignored him.
After performing various tribal rites, she finally handed him to his mother lying on a makeshift bed.
"His name will be Serakhiel," she said after a pause.
The woman seemed to have seen something, and quickly left the tent containing the mother and her infant.
'Th... this child... no, it's impossible.'
Even though she didn't totally believe the perceived vision, she left to inform the tribal chief of the child's importance.
It was her instinct.
The person who plays the role of a Helix-Memorant in the tribe is very important, because she is the memorial guardian and sometimes a pseudo-shaman.
This woman is a latent psyker.
The latter saw enormous latent talent in the mutant child, thanks to her latent psyker gift stimulated by Sanguinius.
Yes, the baby is the former Fallen Angel.
'A... AI Chip, are you done scanning the dialect used by this crazy woman?'
[Affirmative, I'm starting the information transfer...]
Sanguinius learned the unknown language without difficulty and, thanks to the AI, he was able to understand his new name.
Of course, he planned to change it quickly.
'Leaving Damien was annoying and I still have to change? No thanks.'
While he was lost in his thoughts,
the exhausted mother regained consciousness and gave him her breast to nurse.
At first, he was embarrassed by the situation and the quality of the nipples didn't please him because of the rough and not soft skin.
But he ended up drinking because of hunger.
'Fuck!! This is disgusting.'
[Alert!!!]
[You are again irradiated by radiation and you have been poisoned.]
[It is recommended to use your magic to heal.]
'Easy to say, but I have...'
The moment he wanted to use Holy Power, to prove to the AI chip the loss of his powers.
Sanguinius felt like connected to something.
It was a strange sensation, but intoxicating at the same time.
He felt "full" of energy.
'Haa~'
'Kill... kill...'
After executing the healing, he began to perceive various whispers and growls.
Sanguinius immediately stopped using his 'Holy Power', to his mother's great misfortune.
She no longer had rough skin, result of her body's attempt to adapt to the radioactive environment.
She didn't even have the shadow of a scar anymore.
The midwife and the mother stared at the baby, who had just accomplished a miraculous act.
Outside of his wing mutation, the latter had something else... the number 2 on his wrist.
