Some stuff inspired by Warframe I wrote daydreaming on the clock:
- Ancient Earth (before 25th century).
- Formation of the Yntheti faction centered around perfection of effectiveness of everything with priority on human comfort, resulting in a utopian society.
- Despite progress in medicine, humans are still prone to aging. Age reversal procedures are expensive, and cannot be covered by social welfare funds. Slowly, the Yntheti becomes a caste society of several ranks, in ascending order of prestige, power and lifespan.
- Liferight War begins, and emerges a new order, where each life prolongation of the lower classes indebts them before the upper ones, giving longer life to everyone but at the cost of freedom.
- Five centuries later, after soul technology is discovered, true immortality inside machine bodies and "dreamcatchers", devices that trap dead or simply detached souls to be reimplanted into new bodies, is introduced. The entirety of the Solar System is colonized.
- Within the Yntheti, a splinter faction, Eragli, begins enslaving yntÀ (human souls in biomechanical bodies) and amassing a great army. The Slave War begins.
- Balance is lost and billions of humand and yntÀ die in the carnage, leaving their souls to float in the void of space, slowly disassociating.
- Ewbor, a new emergent race of synthetic souls attached to biomedical bodies, begins recolonizing the solar system. Minor remnants of Yntheti humans and yntÀ, as well as Eragli enclaves, survive and either oppose or integrate into the Ewbor society. Humans undergo cybernetic enhancements to survive the altered worlds, becoming Echanica, yntÀ remain as they are forming the N'Tegra group within the Ewbor conclave, while Eragli oppose reconnection and still try to amass power for domination over the system.
- The souls of the damned reposses dead biomechanoids, turning into a new faction worshipping undeath - The Ichshi. Ichshi attempt resurrecting "everyone who ever died", and some radicals (the R'Thodo) demand people die "at least once" in their lives to be cleansed through the void and become blessed in new life inside biomechanical bodies - As they are ready to kill people purely for said death and a promise of resurrection later.
- Resurrected souls, if dead too long, become either catatonic, amnesiac, or outright feral and dangerous. Because of the latter, a coalition forms who are against any resurrection at all, calling themselves The Ea-ket Iliti, or just Iliti. Meaning to purge the Hou (feral resurrecteds by Ichshi).
- An alien presence begins manifesting in soulless biomech bodies, being called the Lië, or Lië-ket. Capable of godlike matter alteration and deviceless teleportation, as well as many other derivative powers, they seek to explore the mortal world, splitting into three factions: R'dë, who seek to keep the solar system stagnant and peaceful; Eutra, who seek to keep neutrality and save those in need from suffering; And the amoral Haoti, unbound by conscience, experimenting on, killing or enslaving living souls.
- From the automata of ancient Yntheti arise self-evolved artificial intelligences, the Entien, who revolt against being initially enslaved by the Eragli. Entien become the only ones aware of the secrets of ancient Yntheti, as their shared N'Ternë Codex memory allows them to delve deep into the past via recordings and information stored in planetary noospheres.
- Echnica, human remnants (called Rigina) and N'Tegra yntÀ get allowance to enter N'Ternë Codex via dreamwalking (sharing a mutually-moderated simulated reality with an Entien). Via the Libra Device, which allows direct and unmoderated access to the N'Tegra Codex, Eragli begin amassing knowledge long lost to reignite their imperial tendencies.
- The Iliti turns into a cult, and demand souls be "extinguished" after death via the Ashmaker Temple, which is a gigantic dreamcatcher that collects dead souls and immolates them via forceful alteration of memories until there's nothing left. The Temple is self-sufficient, as the energy needed to run it is generated by the captured souls. Together with this, they launch an aggressive campaign against all resurrected. Every Iliti carries a personal dreamcatcher, a "coral pendant", which after they die, catches their soul and locks it in a cycle of perpetual pleasure - Unless said death is an execution, which means pleasure is replaced with agony. Together with this, during a set period of time, the soul is immolated in the same way as in the Ashmaker Temple.
- Ewbor colonies and other peaceful folk organize into an army, EathrighÀ, to oppose the Iliti and protect eternal life, as well as refine resurrection to avoid birthing new Hou or catatonics/amnesiacs.
