After some thoughts and discussions, people located J-Space to be somewhere north of old Jovian space, in that general area connecting to their region. J-Space is ruled by sleepers, and their ruling drifters, in all systems. They also have a few systems known as hives, where there are massive portals that go to un known places.
I came up with a theory that explains what happened to the Jovian race , and this explains multiple phenomena throughout new eden.
I suspect that a very long time ago the Drifters and Jovians came in contact, either the drifters were the attackers, or the jove were. They started a war that the Jove lost, and the drifters started to take over new eden.
In more detail, after first contact, the drifters attacked the Jove with a Bio weapon, which is the disease that supposedly killed off the jovians, even though it was a weapon. The Jove fought the drifters north of the home region where new eden is, in J-Space, which explains some battleground in wormhole space, and retreated back home when they found out that a mysterious disease was killing off their people.
The drifters then launched a full on assault into the home region, and it destroyed the the capital systems, which explains carolines star, which was a massive explosion. In the battles the region was destroyed, which is now what we call abyssal deadspace. The gates shutdown to prevent the drifters from coming here, or were destroyed in result of the war.
The jovians died out except for a few, who re made their tech to fight the drifters, the tech is what we now call triglavian tech.
The observatories also de cloaked because of the grid being shutdown, because the jovians watched us for years.
Mutaplasmids are to keep the Jovian from dying
The structures in abyss space are not to kill drones, they are meant to kill the drifter weapons, and thats also why the triglavian ships have so much dps.
