Adam has consulted Jarred multiple times to gain more information about this coming enemy.
The humans who invaded Jarred's world is far more advanced that their war capability. Their technology is way beyond that of Jarred's understanding. His world is a bit more advanced that this world but they have not reached enough technology level yet to fight the other humans.
Jarred's world and its technological path is a bit similar to this world. They both pursue the knowledge about human DNA. In Jarred's world though, there is no zombie outbreak.
Jarred informed him that their world have just achieved its first space flight from its very first space battle Cruiser when the attack came.
Being invaded by a force that developed advance weaponry and have huge war ships, their military were simply no match.
In the end Jarred and his people were forced to use their knowledge about genome and mutated their bodies to its peak. Giving them super strength and speed.
It allowed them to survive but not enough to win the war.
After long years of fighting and war, they were able to capture one of their smaller capital ship.
It has crashed into the side of the mountain during a pitch fight. Apparently, the enemy thought that the ship is already gone.
The Mazoku Tral's captured the ship and activated its transporter. It still has a functioning dimensional transporter on board.
All of the people who fought with Jarred agreed to use the transporter and find a new world.
Having reached this agreement, they then plotted for a way to get their revenge.
After Jarred and his people passed through the transporter, his father who was also the current leader back then stayed behind.
The plan was to use the same dimensional transporter and open a gate inside the known black hole.
This started a cascading event which resulted to the collapse and implosion of that earth, killing every single being there.
...........
Two more years have passed.
During that time, Adam and his people are constantly preparing for the inevitable arrival of the enemy.
The time when their scout ship arrives is getting near.
Once that happens, those people will realize that this world have become a threat and will send their forces here too.
They suspect that it's the military capabilities that those other humans fear. They attack worlds pre-emptively so they won't pose any threat to them in the future.
.........
One of their plans is to unsummon all the capital ships. If the scout didn't see any threat here then by theory they should leave this world alone for another 10 years.
However, if they decide to attack anyways, it will leave this world undefended.
Their final decision was to send all the capital ships far out into space. Probably park all the ships in Pluto with just the AI's for control.
It's also good that Pluto is on the other side of the sun from earth. So the sun is between the two planets. Well apparently pluton is still a planet in this world and not a planetoid like in Adam's.
.........
High up in the snowy mountains located in the northern hemisphere, a huge portal suddenly materialized out of nowhere, blue arcs of electricity can be seen crackling around its edges.
An hour after the portal appeared it suddenly emitted a big energy fluctuation and a five hundred meter long ship burst forth from within.
After it arrived, the ship broadcasted a strange frequency and in a matter of seconds, millions of probe embedded under the ground from all over the world suddenly flew out and zoomed towards the ship.
The probes showed the ship all that has happened to this world for the past ten years.
It got all the images of the war and the humans. At the later parts of the history, it started showing anomalies. It showed things that are not supposed to appear in this world anymore.
Within seconds, the ship sends an alarm using its dimensional communicator.
"Emergent Protocol Activated: Alert the Herald, World Z32-T7651. Prepare the Armada."
