Who is GAIA in Horizon Forbidden West

Whether a player is new to the Horizon series or is still trying to remember what happened in the previous game, many may be a bit lost on who this GAIA is and why she is so important to Aloy's story within Horizon Forbidden West. Several different Greek and Egyptian gods' names are brought up and discussed throughout the beginning of Aloy's journey as we grasp onto how she can save Earth. The thing most players know is that GAIA is what Aloy needs.

GAIA and her primary function

GAIA is an extremely advanced AI that Dr. Elisabet Solbeck and her colleagues designed as a way to reboot the planet after its inevitable demise. Within GAIA, there are nine different subfunctions to terraforming and making a habitable planet. Each of the nine subfunctions has its responsibilities to handle.

The Nine Subfunctions

• Minerva - Responsible for communication and shutting down destructive Faro Machines.
• Hephaestus - Responsible for constructing terraforming machines.
• Aether - Responsible for detoxifying the air and atmosphere.
• Poseidon - Responsible for detoxifying bodies of water.
• Demeter - Responsible for recreating the floral biosphere.
• Artemis - Responsible for reintroducing animals into the biosphere.
• Eleuthia - Responsible for reestablishing humans into the biosphere.
• Apollo - Responsible for teaching humans and preparing them for the biosphere.
• Hades - Responsible for wiping a reboot attempt if it is unsuccessful.

Each within GAIA's guidance made several attempts at rebooting life on Earth within the biosphere. Sadly, as Dr. Solbeck was creating such a powerful piece of equipment, it was heavily sought after both before and after the initial loss of humanity. Due to this, Aloy's quest to reestablish GAIA will be quite difficult.
