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, 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 Oyun's efforts and 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 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.

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 so big because it covers the cavities of the unburied udurgh.

Bachelor Route
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.

The Abattoir becomes accessible to the Haruspex on Day 9: he is pointed there by Oyun, who tells him it is where he will understand what happened to his father. Of its three entrances only the Bulljaw, traditionally the door from which bulls are taken in, is open. On entering, he will be temporarily relieved of all his inventory. Inside the Abattoir he comes to learn the nature of the Plague, the reason why it appeared and why the Kin are not affected by it. He can also obtain more Living Blood from fountains across the chambers. Finally he will be told to stay with the Kin of the Abattoir. The only available exit is a great pit in the ground: jumping down will lead him to the Town's living heart, then to emerge from the well inside Vlad the Younger's Vacant House.

Following this, he finds himself again in the Abattoir during a dream, where he can speak to a number of Albino and Isidor.

Once he has discovered that Oyun was the one to kill his father, he will find him in the Abattoir by the pit and confront him, ultimately deciding Oyun's fate.

In the Nocturnal Ending the Changeling can be found in the Abattoir, along with Sticky and Oyun.
