Sector 1 is one of the eight Sectors that divides the metropolis of Midgar in the Compilation of Final Fantasy VII. The sector is the first location visited in Final Fantasy VII. Cloud and AVALANCHE enter Sector 1 on the train before entering the Sector 1 Reactor. The station is called North Edge Station.
The Sector 1 station provided appears on the edge of Sector 8 and Sector 1. Zack Fair frequently used the station to travel by train between Sector 8 and Sector 5.
AVALANCHE, a terrorist group based in Sector 7 rebelling against the Shinra Electric Power Company, plan a bombing mission in the Sector 1 Reactor. They board the train to Sector 1. From here the small collective make their way into the Sector 1 Reactor.
Sector 1 is an unrevisitable location visited at the start of Final Fantasy VII when destroying the Sector 1 Reactor. A small area of Sector 1 is visited, which is located on the edge of the sector close to the Sector 1 Reactor and the adjacent Sector 8. This area is accessed by train, though the main area is elevated above the train platform.
The areas of Sector 1 that are visited include the platform, a train station reached by a set of stairs, a walled-off area just north of the station, and a walkway connecting Sector 1 and Sector 8 entered in the walled-off area.
The Platform is the first area in the game and visited as soon as the opening movie finishes. The area comprises a stone platform alongside the railway track, with metal gates on the lefthand side, and the sign "1-0b" painted on the wall. At the fair end of the platform on the left is the exit onto the Sector 1 Station.
Two Potion items can be picked up here from the guards. Though both guards can have the items, their items are shared meaning the player can pick up both Potion items from one guard. This is known as the Quantum Potion bug.
The random encounters are available until the player leaves the screen and returns, in the player's first visit.
Sector 1 Station
The Sector 1 Station area is entered from the Platform through a staircase beneath it. Here, the player exits a door and heads north to join with the members of AVALANCHE. The station is a wide, stone building with a gale roof and four turbines on each corner. It is situated atop a stone wall overlooking the railway, and adjacent to the wall surrounding the Sector 1 plate. In the surrounding area is a path north towards a stone wall in front of the Sector 1 area, where the mission continues.
The Sector 1 area is walled-off area reached from the Sector 1 Station. It comprises a few small metal buildings across a stone floor alongside the wall surrounding Sector 1. Within the area are metal pipes, metal framing around the buildings, and dim street lamps. Above some metal framing is a screen, showing the words "INTRUDER", "WARNING", and four Kanji characters. In the center of the area is a narrow building resembling a bunker at its front with a large clock tower at its top.
The Sector 1 area leads to the walkway outside the Sector 1 Reactor, with a walled-off door to the walkway at the very back of the area. The path to this door is found to the right of the central building, after passing it is a path left straight to the door.
The walkway outside the reactor, known as "No.1 Reactor" in the menu, is used to access the Sector 1 Reactor, and to escape. It comprises a metal walkway connecting Sector 1 and Sector 8, and a path in the middle leading directly to the Sector 1 Reactor. The walkway is suspended above a vast abyss over the lower area of the city.
No. 1 Reactor
The Sector 1 Reactor is only visited once at the start of the game, but is destroyed, and cannot be visited again.
The station is a small area that comprises mainly of a straight forward run. On the far south of the area, a door to the east can take the player to the Sector 8 - Fountain area. At the north the player can board the train and it will take the player to the Sector 5 Slums - Market area.
