The 2 Galaxys meet, what goes down
Ok i 100% know this ISN’T original and has probably been done on this sub 100,000 times but i thought i’d give it a go and make CLEAR rules for how the universes react with eachother (The warp, the force, blackstone etc)as well as the different species. i’ll try make the boundaries as clear as possible and clarify if needed.
The Warp (And chaos): The warp will interact with the inhabitants of the star wars exactly how it does with humans in the 40k galaxy, everyone can be corrupted and no one is “immune“ to corruption. This also means that any species can become psykers just as easy.
Pariahs/blanks: For the sake of them effectively being soulless there will be no pariahs in the 40k galaxy unless they are born after the 40k galaxy leaking into the star wars galaxy. However pariahs will not effect the force meaning they have no additional protection from it.
Blackstone/the pariah nexus: Blackstone (like blanks) will have no effect on the force and the pariah nexus won’t affect jedi, sith or the inhabitants of the star wars galaxy.
The force: Unlike the warp no one in 40k regardless of psychic attunement will be a force user unless born after the 2 galaxys colliding. However those born with the powers of the warp or the pariah gene can still be force sensitive.
Humans: the humans in 40k may recognise the star wars “humans“ as actual humans until they do any form of blood/DNA test in which there genes will be deemed as tainted.
Eldar: The eldar will have no connection to the force and will never have a force sensitive due to there very VERY low birth rates.
Tyranids: the nids will be mostly unaffected by this since well it’s just another galaxy to eat, however they won’t be able to create force sensetive bio-forms.
Ok. Now that i think i’ve cleared up the rules i’ll make the scenarios.
Scenario 1: During the early days of the horus heresey the traitors open a massive warp rift that leads to the star wars galaxy during the clone wars. The rift will be located in segmentum tempestus for the 40k Galaxy and the very edge of the outer rim. Exact date i’d say 20BBY for star wars and 007 M31.
Scenario 2: During the opening of the great rift and the fall of cadia when the rift finally opens it also causes a fracture creating a smaller rift (Again in segmentum tempestus) that leads to the star wars galaxy during the reign of the empire i’ll say in 6 BBY
Regarding the sizes of the rifts they’re very large. I cannot even try create a measurement but let’s say they CANNOT go unnoticed.
Go and make thy theories!
Edit: one of you lovely people pointed some things out so i’ll change the rules a bit:
• Eldar can have force sensitive children and can develop force sensitivity overtime but it isn’t at any sort of increaed rate.
• humans can also develop force sensitivity regardless if they are a pysker or blank
• tyranids can create force sensetive bioforms
