Et Deus Factum Est Machina
Awakening
In several parts of the world, genius inventors discover various ways to breathe life into inanimate dolls, automatons and other constructs. The beginnings are hazardous and many accident occurs, but these events marks the prelude of something bigger
With a great steampunk influence, this era is a time when machines are still poorly known but of the greatest sentience they will ever be, before wary craftsmen remove the intelligence, deemed useless in their task.
Devastation
Just after the golden age of robotics, the Devastation is the end of the civilization of man. The rise of the machines began in a blur, and before anyone could react humanity was at war against its very own creation. A losing war, that did not last long.
The shortest era of the four, an utopia undergoing an apocalyptical event, terminator-style. Ruins of avant-garde buildings are the scenery of a desperate battle to survival, one that is already lost.
Remnants
A few centuries later, humanity and robots have both recessed. Tribes of primitive people try to survive the hunt of feral machines thirsting for energy. Power plants left unmaintained for too long scorched the land, and wildlife grow painfully from the nuclear winter. Ancient ruins are inhabited by dormant killers, keeping the advanced technology unreachable.
Post apocalyptic wasteland, the Remnants era is mostly influenced by the world of Horizon: Zero Dawn. Humanity is drawing its last breath, trying hard to survive in a world too hostile for them.
Silence
Humanity is long gone, and so are most machines. They all ran out of energy, unable to produce enough to sustain them. Remains of humanity poison Earth and give a bad time to the struggling wildlife. From time to time, the emergency battery of a robot is reactivated by chance, and it wanders in the empty wasteland for some years before shutting down for good.
The empty end of thing. An era devoid of life and future. The last traces of humanity are dying out, satellites are drawn to crash on Earth and overgrown cities blends in natural hills.
