'I was told that everyone I'd served with in the military died shortly after I left. Today, I saw one of my old squadmates, homeless, digging through the trash behind a convenience store. He had an unbelievable tale to tell.'
The First World was a universe existing at the centre of the Multiverse structure discovered by Heath. While affected by the spatial rupturing caused by The Crushing Fist, it was better protected than the other multiverse realities contained within the Outer Shield due to the existence of an additional golden Inner Shield. This shield could only be penetrated by specific signalling devices that look like Metallic Chips. The First World had previously been allied with the Brownshirts, who at the time were a society of ascended beings of pure energy. The Brownshirts helped create the mechanisms that generate the shields and also helped grow the branches of realities known as the Branch Worlds.
This reality was largely populated by the rich and powerful, and its inhabitants were well aware of the existence of the multiverse and The Crushing Fist. They also constructed many Portal hub facility type sites which are used for interdimensional travel, as well as other military installations. The military of The First World (Command) were the maintainers of the Inner Shield and Outer Shield which protects the grouping of universes populated by humans.
Due to its existence within the Inner Shield, The First World had become a focal point for the force of The Crushing Fist. The vast mechanisms generating the two shields were under immense pressure, which would normally be distributed and dispersed to the Branch Worlds. As the force continued to rise, the compression was concentrated by the multiversal structures directly on The First World itself via the Inner Shield. This caused a significant amount of heat to be generated from the shield generator machines, disrupting normal weather conditions on the world. Eventually a White Hole formed as the Inner Shield failed.
The First World maintained a presence on numerous nearby parallel and pocket or shard universes, which are used for agriculture, resource gathering, or in the case of Teskoy Prison, a penal establishment.
Prior to its destruction, the First World was at war with the Yngtak for a very long time, with Conn Thompson describing them as eternal antagonists to The First World. The war is presumed to have ended with the subsequent destruction of the Yngtak universe as well as The First World.
The First World was destroyed after the Inner Shield began to fail, forming a White Hole. In an effort to disperse the White Hole, Cristina Thompson detonated a Dimensional Fracture Bomb to attempt to relieve the pressure, however due to the compression of The Crushing Fist, the Inner Shield failed by collapsing inwards, instead of exploding outwards. The dimensional rifts caused by the bomb also shattered the Moon of The First World, which was due to collide with the surface, eradicating all remaining life. Cristina Thompson and Thomas used the effects of the Soul Reader (Book) on a Portal to facilitate a disorganized mass-evacuation by generating a world-wide portal storm.
