Cauldron EPSILON was a location in Horizon Zero Dawn: The Frozen Wilds, located within the 21st century facility known as Firebreak.

Description[]

Before its destruction, Cauldron EPSILON was located at the very back of Firebreak's Battery Facility, and served as the manufacturing facility for the Daemonic machines found within the Banuk region of the Cut. It was also a research and development facility where its creator and overseer, HEPHAESTUS, embarked on a drive to develop hunter-killer machines to hunt and kill humans.

Like other Cauldrons, the design of Cauldron EPSILON heavily features geometric patterns, especially triangles. However, as the first known Cauldron designed solely by HEPHAESTUS, EPSILON differed from other Cauldrons in a number of respects. Besides being the largest Cauldron by far, EPSILON was built over the pre-existing Firebreak facility and parts of an active (albeit controlled) volcano, Firebreak components make up a noticeable part of EPSILON's infrastructure, and parts of the volcano have been left untouched in the construction. The compromised parts of Firebreak are surrounded by purple wiring, reminiscent of a parasite.

Rather than the pale blue lighting typical of other Cauldrons, most of EPSILON's lighting is a deep purple.

History[]

EPSILON CYAN Hub

CYAN under the control of HEPHAESTUS.

Cauldron EPSILON was built by HEPHAESTUS, a former subordinate function of the Zero Dawn terraforming system's governing AI GAIA. Having chosen the location due to the natural geothermal energy and mineral resources available from the magma that the facility tapped into, HEPHAESTUS commandeered the Firebreak facility, enslaved its governing AI CYAN, and built the Cauldron. There it set about developing even more aggressive and dangerous machines, including commencing research and development of hunter-killer units to eliminate humans.

Horizon Zero Dawn: The Frozen Wilds[]

However, HEPHAESTUS' actions against CYAN drew the attention of the Banuk shaman Ourea, who had formed a strong bond of friendship with the AI before HEPHAESTUS enslaved it.[1] This culminated in her forming an expedition consisting of herself, her brother Aratak, erstwhile chieftain of their werak, and the Nora Seeker Aloy.[2] Led by Aloy, the party successfully infiltrated the Cauldron. Ourea overrode its core, albeit at the cost of her life, freeing CYAN. CYAN caused the Cauldron to self-destruct, foiling HEPHAESTUS' plans.[3]

Due to EPSILON's destruction, the door that led to it remains permanently closed.

Horizon Forbidden West[]

During their altercation in Repair-Bay TAU, HEPHAESTUS recognized Aloy as the destroyer of Cauldron EPSILON.[4]
