Abattoir

"An ancient temple turned into a slaughterhouse. A place where the town’s zoomorphic nature is particularly salient. A theme of nestedness: as the town had grown atop the bull of the earth and crushed it down, so has the gray-concrete Termitary, housing the workers, grown atop the Abattoir, humanizing it and taking away its magnetism."

- [from the game’s design documents]

The Abattoir (Бойни), also known as Olonngo, is the womb from which the whole city was born, the heart of the Bull Project (the economic basis of the city) and the "neolithic swelling on the edge", as the Bachelor puts it. The Foreman is the main link between the Abattoir and the Town.

Description
The Abattoir is the core of the Bull Enterprise and the place where the bulls are slaughtered. It is said the Abattoir's transformation into a prosperous industrial facility (that simultaneously remains a pagan temple where Steppe rites are performed) is due to Foreman Oyun's efforts in working with Big Vlad.

The Abattoir can be accessed through one of three gates: the Gates of Labour, which are used by the workers; the Gates of Sorrow, through which slaughtered bulls are taken away by the railway track; and the Gorge (or the Bulljaw in Pathologic 2), a corridor in the depths of the Abattoir, the route that Supremes take when they come from the Steppe to be celebrated. There's also a passage to the Abattoir from the Termitary. Entrances to the Abattoir are limited, and getting there is not easy. Butchers cover the gate with boulders and at the right time, they roll them back. Opening and closing the gates is subject to complex laws established by the Foreman. Previously, it was run by Father Superior Tycheek, and it is now run by his daughter. According to Aglaya Lilich, it is impossible to enter into a slaughterhouse when it's off limits due to an overwhelming mental barrier.

Pathologic
On the day of the Inquisitor's arrival, at her command, all the gates are opened. However, the Butchers and Worms inside the Abattoir will be hostile to outsiders.

Local kids believe the Abattoir is inhabited by gods so old that beasts used to believe in them before humans even came to exist. Some townsfolk say the Abattoir is so big because it covers the cavities of the unburied udurgh.

Over the centuries, butchers poured ritual bovine blood under the Abattoir through various underground cavities, causing all the ground under the town to be soaked in it.

In the depths of the Abattoir, Haruspex is able to find the living blood, which he uses to create the Panacea. Aglaya Lilich suggests that the Polyhedron caused the wound in the earth which prompted the infection, therefore removing it will save the town.

The Bachelor insists that the Plague was born underground in the temple, in mineral deposits, so with its soil poisoned, the Abattoir and the Town must be destroyed to eradicate the disease and the blood that has gathered below.

Bachelor Route
On Day 6, the Bachelor can find the Albino wandering in the Steppe near the Gates of Sorrow. Var and his arsonists will attempt to launch an attack on the Termitary at the Gates of Labour.

On Day 8, the Bachelor can convince Taya Tycheek to give him access to the Abattoir by exchanging one of the Olgimsky men, or by retrieving her toy from an infected house. The Abattoir will open at 23:00, and entering will lead to a cutscene of the Bachelor being accosted by Butchers for trespassing. He is rescued by the Army and will regain consciousness on Day 9.

Haruspex Route
On Day 7, the Haruspex learns that the Abattoir has been opened again and enters to meet with Foreman Oyun. He will receive a vial of Abattoir Blood.

On Day 8, the Inquisitor asks the Haruspex to enter the Abattoir, but finds that it has been closed once again. The Haruspex must find the Changeling and trick her into telling him the true ending to a story for Taya Tycheek in order to reopen the Abattoir. Once inside, he speaks to Oyun who tells him that he is not ready to fully accept his inheritance. The Haruspex must speak with Aspity and receive the Bone Horn before returning to Oyun again.

On Day 9, the army Commander Alexander Block will ask the Haruspex to enter the Abattoir. After speaking with Oyun, the Haruspex's exhaustion suddenly begins to rise as part of his trial. In order to complete the trial, the Haruspex must find the Bachelor and return to Oyun.

On Day 10, at the Bachelor's urging, the Haruspex enters the Abattoir again to speak with Oyun. Oyun gives him another trial in which he must capture several Butchers who have violated the Law while experiencing starvation. After finding and killing all of the Butchers, the Haruspex returns to the Abattoir and speaks to Oyun to complete his trial.

Changeling Route
On Day 8, the Inquisitor asks the Changeling to investigate the Abattoir. The Changeling convinces Taya Tycheek to allow her entry by telling her a story. Inside of the Abattoir, the Changeling will encounter Foreman Oyun.
