Adeptus Astartes/ Space Marines

The Emporer's third attempt to make his perfect soliders. He knew he wasn't good enough at gene manipulation to make what he was looking for, so he made a deal with the Chaos Gods. They would give him the ability to make the Primarch's and Gene Seeds. He was suposed to give them something in return but didn't. This pissed them off.

Using Erda's eggs and his own DNA, he created 20 sons. He then geneticly altered his sons into wepons of war and extracted their DNA to make super soliders. Erda saw this and wanted to protect her sons from they're evil father. However she wasn't powerful enough. So instead she sent them into space and hoped for the best.

This unintentionally put them in the clutches of the Chaos God's. They grabed the Primarch's pods and put them in the warp. However even the Gods can't fully control the warp. It sent each Primarch to different planets all over the Milky Way.

Soon after this the timeline warped, temporarily making the Emperor seemingly **** to Slaanesh. However while she was trying to posses him, they accidentally fused into 1 being. The Empress of Pleasure.

After convincing the Emperor of Mankind's allies and armies to fallow her, next was what to do with the Space Marines. They're not as powerful as the Custodes but she can make more of them faster and they're stronger then the Thunder Warriors. So of course she would want to use them. However she rembered a problem. The process to make Astartes makes them sterile and they are hypnotized to never want sex. This is because the Emperor didn't want them to replace humanity.

(So after learning the Sisters of Battle aren't geneticly altered, I serched high and low for any other factions that are genetically modified and are allowed to have sex. I double checked to make sure Custodes aren't allowed to breed. They're not. I checked to see if the Thunder Warriors can have sex. I didn't see a rule saying they weren't allowed but I did see something that said they where sterile. I checked if any other faction in the empire where genetically modified. I only found1 individual. I single Inquisitor named Hector Rex. However I can't find anything to do with him have sex.

So if the Emperor did know how to make his modified boys make unmodified offspring, he definitely would have it so there would be no risk of none human offspring. So the only hope is the Slaanesh half. Unfortunately all 4 chaos gods gave they're help with the Primarch's. If only 1 was needed, the others wouldn't want to waste they're energy.

So would the other 3 help the Empress with this? Well when Tzeentch was the most powerful chaos god, the other 3 teamed up to kill him. The only reason they stopped is because he gave up enough of his power so he was equal footing with them again. I don't think the Emperor was as strong as any of the Chaos gods since he was so scared of them, but I do believe he was close. So the others are definitely gonna want to team up and kill the Empress unless she somehow unfuses. Them fusing is the entire premise of this book so I'm never going to make it possible for them to unfuse.

I only want to chage things if it comes naturally to the chage that started this book. Well making the Empress good enough at gene manipulation to do this feels wrong. So for now at least they'll remain sterile. I'll look to see if there are any better characters at gene manipulation that might be willing to help her though. Sorry for the long tangent.)

Well she's not good enough to make them fertile again. The Emperor didn't want his super humans to replace humanity and Slaanesh gains power from pleasure, not the baby making itself. So the Empress won't risk it. She can fix they're possible erectile disfunction though. If they don't have a erectile disfunction, then chaging the hypnosis will do the trick. Being part Emperor of Man Kind, the Empress wants whats best for humanity. So hypnotising an underaged boy into wanting more sex is out of the question. So instead the hypnosis will happen on the Space Marines 18th birthday. However the space Marine will be able to control this erge during combat.

Now that The Empress has what she needs from Earth, all thats left is to wait. Wait for her perfect army to grow into men. Then she can start her crusade. She will Concor all of humanitys lost Colonies and find her lost Sons.

(So hears the plan. First I'll write a chapter talking about the Primarch's life before the Empress finds them. Then I'll make a chapter about what they're leagon is like before they're corresponding Primarch is found. Then I'll make a chapter talking about they're time together before the Heresy. Then finally what each Primarch and chapter are like during 40k since the Heresy isn't going to be as big a problem it is in canon.)
