AUs for my AU
'A Guide' AUs:
The Kidfic AUs:
Lone 40k Kid:
Robu reborn in his same timeline but in the past. Still in the 40k universe but as a kid still.
The idea is that Emps, with the Great Crusade coming to an end, decided that his kids needed something to keep them occupied. He noticed that most of his kids had both paired off with one another and truly loved their Geneseed Sons. So he made the 2nd Gen Primarchs. Children of the Primarchs with other Primarchs.
Did he talk this over with anyone? No. Did he keep the project hidden away to make sure there wasn't a Great scattering 2.0? Yes. Should he have told his sons before heresy? Also yes.
What happened to the 2nd Gen was something that was lost in the Siege of Terra.
Emps took it to his living tomb and the children were no more.
But!
Robu dies, killed by the High Lords of the Terra, goes through the Warp and ends up in the body of one of the 2nd Gen.
Lets say he ends up in the body of the son of Snaguinius and Horus. Ya know, the one kid that started off the whole thing? The Pairing that Emps had noticed and knew of their love not only for each other but for their sons? The one that did end one killing the other? Yeah, lets say he's their kid.
And we'll say that the Dark King and Star Child are not one Being but Two and they loved their son turned Grandson.
Robu will still take the Robel name. He will still turning to bounty hunting and he will still travel. He will find his Great Uncle Mavrick, after of course, stealing him from Trazyn. And he will travel with a Krieg and a Cadian. Why? Because Dark King and Star Child left him alone once and he was killed by the High Lords of Terra and before that he took on a chaos corrupted Fulgrim. Both things he walked into willingly. Both things that did not turn out well for him.
So Dark King takes the form of a Krieg Soldier and Star child takes on the Cadian one.
(the reason they can take form in the material world is because they were born of the living and not of a concept. They still have a living form. They have sons with their blood, sired not because of warp but because of the literal seed and egg combo. They can do so much more because of that, interacting with the material world was just the tip of the iceberg, and the Chaos Gods haven't put that together. It's also a major weakness. But Shush on that.)
I can see a few thing happening is this AU:
Robel waking up in the Palace of Terra. He gets pulled out of the Cradle by Dark King and Star Child and sees the Cradles that have been destroyed in the siege (parts of the Palace came down in the siege and have just been left in where they were, corridors that have not been touched in 10k years and the labs were hit by failing structures. The ceiling came down and took cradles out, others lost life support, either way Robel is the only survivor)
He, when he gets his feet underneath him, steal a ship and head out with Father(s) turn Grandfather(s) (He might take a custodes with him might not)
Gets into bounty hunting
works with Astartes
Gets the Red Thirst and hints of the Black Rage
Makes them seek out the Blood Angels
Dances around the fact that one: Robel is a Primarch, two: the Son of Sanguinius, three: the Son of HORUS
Can't let that last part get out
The Blood Angels aren't much help when they don't know they suppose to help
Guilliman starts getting reports about a Bounty Hunter that never fails a hunt
Hires them to hunt down something
They do not meet but Robel starts to help out around the Imperium solving issues that fucked him over when still Roboute
Gets stuck in a war zone with Astartes
Primarch status blown wide open with everyone having an idea on what the two soldiers at his side are
Maverick fits somewhere is the mess
Oh and so do the 2nd and 11th
===
Keeping in line with the Idea; everything is the same but Robel isn't the only survivor of the cradles and that Emps can't help out as much.
Au 2: The Children of the Primarchs
Sanguinius was the most beloved of the Primarchs. Every Primarch loved him. So when the Emperor of Mankind was making the Son of Horus and Sanguinius and the fear that his other children might feel left out and scorned for not having their own children; it wasn't a jump to make Sanguinius the 'Mother' as it were for many children. It wasn't to say that there weren't children that didn't have his DNA acting of the egg as it were, there were pairings that didn't have Sanguinius involved.
It was just he was main base.
Because if the other parent did not love his children then Sanguinius would be there to love them all the same.
Too bad the Hersey happened.
The list of Children: Oldest to youngest with parents
Robel (Son of Horus and Sanguinius)
Rats (Son of Konrad and Sanguinius)
Bones (Daughter of Russ and Lion)
Med (Son of Mortartion and Sanguinius)
Tinker (Son of Fulgrim and Ferrus)
Lilac (Daughter of Angron and Sanguinius)
Harthas (Son of Corvus and Konrad)
Bam-Bam (Daughter of Magnus and Khan)
The Twins: Tarasha and Kondora (Daughter of Roboute and the Missing Primarchs)
Tactic (Son of Dorn and Perty)
... (Sons of Lorgar and Angron, Lorgar and Sanguinius, Daughters of Alpharis and Horus, Omegon and Horus)
They were not all born at the same time. Robel, slowly gets those that lived, out of the cradles.
Rats is a seer and is Robel's right hand man.
Bones is the enforcer for Robel's rules and is the hunter.
Med is the medic of the group, had a really good understanding of medical things.
Tinker builds things.
Lilac keeps the peace.
Harthas handles the cooking and is also the spy master.
Bam-Bam is the psycher with the tendency to hit anything and everything with floating objects.
The twins are toddlers but bring joy.
Tactic stays wrapped up in a sling to Robel's chest because he is a newborn baby.
'...' do not make it. They come out of the cradle, they live for a few days, but for different reasons they do not make it.
Maybe one of the '...' died because of something in the Palace. Maybe a serf killed them thinking they were a mutant and not a 2nd gen Primarch, because why would they think that? The kids live in the walls and vents but Robel know that is not a safe place to raise children. After the death of '...' it is even more so.
So Robel packs up the family and leaves Terra. He steals a ship, but had no idea of where to go.
Bam-Bam had read in a book somewhere about oceans; Bam-Bam wants to see an ocean.
Bones wants to hunt a great beast.
Med wants to sleep under the stars.
Tinker wants to build a house. A big house where they can all live together.
Lilac had heard the serfs talk about a festival held on a planet that was all about flowers. She wants to see that.
Harthas wants new recipes to cook.
The twins and Tactic are just happy to be there.
Rats has a knowing look in his eyes. But doesn't argue when Robel's say that that is what they will do! They have dreams to fulfill and the galaxy to explore.
Later, when all but the oldest two are asleep, Rats will tell Robel what he had seen.
(Rats, because he is the son of the two seers of the Primarchs, doesn't just see one path into the future, he sees all choices and the effects they have, laid out in front of him. He knows his brothers, the Night Lords, will come calling. Nearly all the paths lead to that. He sees chaos and the Imperium take notice. There wasn't a path they stay hidden and alive in the palace. He sees Primarchs staying in chains and other times he seen them free themselves because of children they haven't even met. He sees the Blood Angels find out about them. He fears the day he will see the Blood Angels find out about Robel being the son of Horus, he dreads it.)
Geneseed brothers will not leave them alone.
Robel nods.
He will not let chaos have his children.
And they are his children now.
Even though he is a child himself.
The Plot is a simple field trip across the Imperium and leaving confusion in their wake.
Robel tries his hardest to fulfil the dreams of the kids as they travel.
They cause shenanigans wherever they go (eating contest won by children, machine being fixed by children, causes fights between crime lords in hive cities, food fights that take over a cafeteria, races in flying cars, ects.)
They get reputation
Robel checks off everything off their list and then adds more things
An Eagle shows up; it glows gold and speaks with it's mind (it's Grandfather)
The Night Lords show up and get them out a sticky mess
Rat bites someone's finger off
The Red Thirst comes knocking
Someone gets wings
Bones scares the shit out a Dark Angel and/or a Space Wolf
Harthas steals things that they need (meds and food mainly)
The Twins and Baby are nearly kidnapped
They raise hell to get them back
Roboute finds out about them
Chaos finds out about them
There is a thing called pulling a Sanguinius (Standing your ground at your own gates of Eternity then marching to your own certain death)
Robel is his father's son, no matter what father it was
There were three facts about Robel that need to be stated.
One: Robel loved his brothers when he was Roboute
Two: That love did not fade
Three: He loves the kids in his care as much as his brothers
When push comes to shove, Robel will also put them above himself, no matter what.
When they were being hunted by the High Lords of Terra, who would having a Primarch under their thumbs no matter if they were a child or not, and there was end in sight.
Robel sent them ahead as he stayed behind to hold back an army. (Rats had to be knocked out by Bones who had tears in her eyes as she threw him over her shoulder.) Maybe as he stood there someone tall with wings was seen at his side (Sanguinius stood tall even as his death came closer and closer, Robel was always his father's son.) Maybe as he stood there in the valley, waiting for an army to come down the one path there, he hears the sounds of engines. Maybe instead of the Black Crusaders that he had gotten use to see on his tail, it's the Luna Wolves. (The High lords and the Inquisition wasn't the only ones hunting the Children, the Four were trying their hands and Abaddon said no.) No longer was those that joined Horus and his Heresy wore black. They were going to die here and they were going to die wearing the colors that once did the Imperium Proud. (It did not matter if they were not the Geneseed of Horus, all that matter was they were loyal to Abaddon and had forsaken the Four, if you did? You wore the colors of the Luna Wolves)
Maybe that would be enough to turn the tide.
Maybe it won't.
Maybe Robel would be the last to die. Maybe he held off death long enough to see the sun raise and Primarchs come to the rescue. Maybe, when he saw Mortartion and Magus close portals, when he heard the wolves howl, and when he saw the Red of Blood Angels and Gold of Custodes and the Blue of Ultramar, when he saw Roboute and Leman come around the ben, that was when his knees gave out.
Behind him somewhere, hidden in a cave, unhurt but scared to death's door, was his kids. Kids that were now safe.
Maybe he was gathered up in arms as his hearts slowed. Who picked him up was up in the air. Roboute? Leman? Mortartion? Magnus? Lion? Maybe it was Dante.
The Blood Angel that had been on his tail. The Blood Angel who heard of his Primarch Brothers in a dream from his father. The Blood Angel knew his brothers other fathers but felt no Rage.
The Blood Angel that cradle his brother in his arms and plead with him to keep his eyes open.
The Blood Angel bowed his head and prayed that his father would guard the gate to where the slain go with everything he had, because this should not be the fate of his brother.
Maybe he wakes up.
Maybe Robel doesn't.
Children gathered into arms of Geneseed brothers and Fathers that never knew them.
All the while a Golden Eagle flies above with tears falling.
This AU can have a few branches that break off into their own AUs. One of which is all of the above but somehow they end up in the 30k canon before the Heresy.
I think this would be the one would be written out of order like my drafts but that would be the main thing of it. Like it's the memories of Robel playing as he stands at his Gates of Eternity.
I think the dead Primarchs might show up but I'm not sure. But all Primarchs will come back together to raise the children that is for sure. I'll come up with more details later.

Last AU
The Adult!Robu 30k:
When Roboute is killed by the High Lords he ends up in the 30k, but not as a child but in his old body.
He ends up as his younger self.
He had two choices: one, work to stop the Heresy, or two, not give a shit and let it play out and guard his people.
His brothers never truly cared for him. No matter how many olive branches he held out. They only cared about his planets and how many supplies and men he could muster.
So maybe Roboute, with the scar that killed him carrying over and thus messing up his throat and voice, stopped trying to make it work with his brothers.
The Ultramarines do not pull away but they do not offer up anything that was more then what was expected. Tactics are the same but there is a shift on how battles are handled.
While this is happening, Roboute is working himself to death. He stops eating as much, he looses weight fast, he stops sleeping and lives off recaf. (he use to the armor of fate keeping him alive, he used to running a shit show that was falling apart at the seams with no help.) His hand tremble and he can't look his sons in their eyes not anymore at least. (He had just gotten used to the idea that they are all dead and now they are alive well. it was hard to handle.)
It got bad. Really bad.
Maybe Roboute gets sick. A fever that settled in and refuses to leave no matter what. And it doesn't help that he worked himself into passing out.
His Sons are besides themselves in worry and reach out to the closest Legion. They don't a reply, they try again, nothing. One last time, nothing.
From here this can go three different ways: One, the Ultramarines send someone to Emps to get help, Two, they go to the closest Legion and try to talk to the Primarch personally, three, they stop reaching out and try to help their father father by themselves.
If they go to Emps, then Emps steps up to be a better dad and notices that Roboute his show all the signs of untreated depression and maybe so other issues. His brothers notice that emps his keeping Roboute close by and get jealous but after finding him in the sick bay and not getting better – they get their shit together.
The third option, is the one were the end up being called to back up and/or get one of the other Primarchs out of a bad situation. Roboute drags himself out of his bed and puts on armor and saves the day. He passes out after the threat is gone and his hauled back to his ship his brother, a brother that is pissed they were saved a 'weak' brother, only to find out how bad his health really is. The brother demands why they have not reached out. They have, no one answered.
Brother gets pissed and takes the ultramarines under his and his legions care.
Roboute doesn't get any better.
Brother tracks down the brother that ignored the call for help and tears him a new one. Guilty, the other brother offers help, and from there the plot gets messy. I want a moment where Roboute calls out the 2nd and 11th Primarchs, like the fever is so bad he's dreaming of memories long gone. I want the Emps to hold his hand as he whispers, 'They killed me, those High Lords, really did it.'
The second option, I can see cause the most issues for the brothers at least guilt wise. Like the Blueberries knock on your door and ask for you to hear them out and they don't leave. No matter what you say. Finally, he drag them back to their ship and demand to see Roboute (at this point it's been a few months; it's not good) and when you do see your brother.
Death had warmed over.
Roboute is a literal few days away from death and no one knew of it other then his sons.
Que panic. Que Panic calls from the ship, only because they are from the Blueberries, they go ignored. The brother goes back to his ships and hails Emps.
Emps gets there but Roboute had to be thrown into a statis to save his life. (He struggled, as much as a dying man could, he was begging and it hurt his brother hear him do so, he was begging to die. To not be put in the statis.)
Plans are made and a brother slowly gets more and more enraged at the disrespect the Blueberries get because they are Roboute sons. Emps notices too and tell Malcador to start call the Primachs.
They are have a new counsel but don't tell them what it's about.
Thats all that I have for that. I think I want Roboute to be so weak he has to have help, like he's in a wheel chair or something and Emps watches him like a hawk. The moment a brother steps out of line, makes any move of threatening Roboute, and he interferes.
The brothers have to learn to be brothers.
