The Collapse
The end of the old world began when reality fractured under the weight of Etherium.
The Collapse refers to the cataclysmic era that reshaped human civilization following the uncontrolled spread of Etherium contamination. This historical turning point marked the end of the old world and the beginning of humanity's confinement within New Eridu. It represents both a physical disaster and an ongoing existential threat, as the mysterious energy source continues to warp reality into dangerous Hollows inhabited by hostile Hounds.

Lore & Background
Etherium was discovered as a revolutionary energy source, promising to solve humanity's power crisis. However, its interaction with biological matter proved unpredictable and destructive. Those exposed to high concentrations underwent horrific mutations, becoming mindless predators known as Hounds. Simultaneously, pockets of reality tore open, creating Hollows where physics no longer applied. The Collapse was not a singular moment but a spreading infection that consumed cities over time. As infrastructure failed and populations fled, New Eridu emerged as the final stronghold. The city's administration now strictly regulates Etherium usage, yet the energy remains vital for defense systems and daily life, creating a precarious balance between survival and corruption.
Reader's Guide
The catastrophe began when Etherium, a potent energy source, was first harnessed by humanity in the distant past. Initially hailed as the key to limitless power and progress, its volatile nature soon became apparent to scientists and engineers alike. Uncontrolled exposure caused reality itself to fracture, spawning distorted dimensions known as Hollows that appeared without warning. These rifts consumed entire cities and twisted living beings into monstrous Hounds driven by primal aggression. As the old world crumbled under the weight of these anomalies, desperate survivors fled to the fortified city of New Eridu, the last bastion against total extinction. The Collapse was not a single explosion but a creeping doom that swallowed nations over time, leaving ruins behind. Now, decades later, Etherium remains essential for daily technology yet dangerous in its raw form. Proxies risk their lives entering Hollows to retrieve resources and rescue trapped individuals from the distorted zones. The crisis defines modern existence, forcing humanity to balance survival against the corrupting influence of the very energy they depend on to maintain their walls.
