The Dark Territory was a region on the Island home to the Black Rock and Rousseau's camp and where the Monster was highly active. Its location was several hours somewhere northeast of the survivors' camp.

Territory's name[]

This region was apparently named by Danielle Rousseau, who called it the "Territoire Foncé". On her map she labeled it, "L'ENDROIT LE PLUS DANGEREUX" (Translated: "The most dangerous place"). ("Whatever the Case May Be").



The Black Rock

The Black Rock[]

Main article: Black Rock

Danielle Rousseau took the survivors into the Dark Territory to retrieve sticks of dynamite from the Black Rock, a ship that was located unusually deep in the Island's jungle. ("Exodus, Part 1")

The Monster[]

Main articles: The Monster and Blast door map

The Monster appeared to be more active in this region; it attacked the survivors during their mission to retrieve dynamite from the Black Rock, nearly pulling Locke underground. ("Exodus, Part 2")

The blast door map contained the phrase, "Primary nexus of Cerberus related activity", in close proximity to the Black Rock. ("Lockdown") Carlton Cuse and Damon Lindelof confirmed that "Cerberus" was an alias for the the Monster at Comic Con 2007's Lost panel.

The Temple[]

Main article: The Temple

Rousseau claimed that Montand lost his arm in the Dark Territory ("Exodus, Part 1"). Jin saw Montand lose his arm at the Temple ("This Place Is Death"). Thus, the Temple must have been within the Dark Territory. Robert also later claimed that the Monster was a security system guarding the Temple, and the Monster did indeed pull Montand inside the Temple. This showed that the Monster was more active in the Dark Territory region as it used the Temple as some kind of base.


Main article: Hy-bird

The Hy-bird was first seen by Hurley, Jack, Locke, and Kate while on their way back from a trek to the Black Rock that Rousseau led them to in order to gather dynamite with which to blow open the Hatch. ("Exodus, Part 2") Weeks later during a journey across the Island, as the "Hurley Bird" swooped down from a perch, it made a cry that Hurley said sounded like his name. Michael also tried to shoot it before realizing his gun was not loaded. ("Live Together, Die Alone, Part 1")

Before the crash[]


The Monster drags Montand into the Temple wall. ("This Place Is Death")

The Bésixdouze expedition was heading towards the radio tower, led by Jin, when Nadine went missing. The group searched for her in the Dark Territory, and encountered the Monster. The Monster dragged Montand to a temple, and attempted to pull him inside of a cerberus vent. The science crew tried to pull him back, but the Monster ripped off one of his arms, succeeding in dragging Montand into the vent. ("This Place Is Death")

After the crash[]

The survivors of Flight 815 were known to have visited the Dark Territory on two specific occasions, both times to visit the Black Rock. The size and boundaries of the Dark Territory were unknown, so it is quite possible the survivors may have passed through the region on other occasions.

Season One (Day 44)[]

Rousseau led Jack, Kate, Locke, Hurley, and Arzt there in order to obtain dynamite from the the Black Rock. ("Exodus, Part 2")

Season Three (Days 88-89)[]

Locke led Sawyer to the Black Rock in the Dark Territory in order to manipulate him into killing Anthony Cooper. ("The Brig")

Season Five[]

Ben and the Man in Black, in the form of John Locke, went back to the Temple wall and entered it. Ben was separated from Locke, which allowed Locke to take the form of the Monster and judge Ben in the room below the tunnels. ("Dead Is Dead")

Season Six[]

Jin led Jack, Kate, Hurley, and the wounded Sayid to the Temple per the instructions of Jacob. They found Montand's dead body and the hole that Ben fell through to be judged by the Monster. The Others captured the group and brought them to the Temple. ("LA X, Part 1")

Later on, Hurley, Richard, Jack, Ben, Sun, and Frank returned to the Dark Territory for the final time to get dynamite from the Black Rock, before Hurley blew it up. ("Everybody Loves Hugo")
