Machines are the technologically advanced, mechanized creatures which are the dominant species of the Horizon Zero Dawn world. They typically bear strikingly similar designs to various forms of wildlife, such as avians, ungulates, and even dinosaurs.
The first machines were created by Faro Automated Solutions as domestic servants, the Focus, and @lfred. However, Faro soon began developing machines built for combat, two of which were the Scarab and Khopesh, heavily-armed robots that could supplant entire armies, convert biomass into fuel, and replicate themselves allowing them to operate indefinitely.
The Faro Plague
However, a “glitch” in the Faro machines caused them to ignore commands and begin attacking humans without authorization. The machines replicated faster than they could be destroyed, and began operating as a swarm. Soon, a full-fledged war between humanity and robots began, costing millions of lives and immense destruction. Despite humanity’s best efforts, the swarm could not be contained and they devoured biomass wherever they went, eliminating entire cities and ecosystems. Ted Faro, the CEO of Faro Industries, met with a former employee named Elisabet Sobeck in hopes of containing the swarm, but Elisabet found that there was no way of stopping the machines from destroying all life on Earth. However, she proposed a project named Zero Dawn to Ted, stating that it was the only way of ensuring that life on Earth could continue after the machines killed everything.
Zero Dawn was the development of an advanced intelligence known as GAIA that would crack the machine swarm’s encryption codes, deactivate them, and then re-seed the Earth with plant, animal, and human life. GAIA was aided by 9 subroutines, one of which was HADES, a subroutine that was designed to take control of the terraforming and start it over again if it was unsatisfactory.
The swarm eventually devoured all biomass on Earth, but GAIA managed to succeed in cracking the encryption codes and shut down the Faro machines. She then created many different machines modeled off of former animal life to purify the Earth’s toxic atmosphere and biosphere. Hundreds of years later, humans were released from the cradles they were created in and began forming primitive tribal societies, not knowing of the “old ones” who came before them. The machines they encountered were docile and generally harmless for many generations. However at one point, an unknown signal caused HADES to go rogue and begin his extinction protocol. HADES attempted to take control of GAIA completely, but GAIA self-destructed before he could do so.
The destruction of GAIA meant that every subordinate function of Zero Dawn had to make its own decisions, including HEPHAESTUS, which perceived the human practice of hunting machines for resources as hostile activity. Because of this, HEPHAESTUS made the existing GAIA machines hostile to mankind, as well as creating a new generation of machines designed to attack humans in an event that came to be known as The Derangement.
Machines in the present day are often hunted for their parts and to cull them before they can threaten local populations. They can usually be found in large groups, although some operate in smaller packs. Machines will either run away from or attack humans that they come across, and will completely ignore wildlife. They will never attack each other unless overridden by Aloy or corrupted by the Eclipse and their machines.
