Sector 7 Sector 7 is one of the eight sectors of Midgar in " Final Fantasy VII " . It also appears in some form in " " , " " , and " Dirge of Cerberus - Final Fantasy VII - " . The Sector 7 slums is the first town visited by the party after the attack on the Sector 1 Reactor , and is AVALANCHE ' s home base and an unrevisitable location . The most prominent location is Tifa Lockhart ' s 7th Heaven bar . Denzel was born on Sector 7 Plate . Like every sector , it exists as both part of the slums and part of the plate . Only the slums section is ever shown in any " Compilation of Final Fantasy VII " media . Story . In 1992 , Ifalna arrives on the Sector 7 Slums train station with her daughter Aeris , but passes away entrusting her daughter to a passerby called Elmyra Gainsborough , who had come to the station to wait for her husband who was away at the Wutai War . Elmyra ' s husband never returned , and she took Aeris home with her to Sector 5 Slums . In October of 0007 Tifa finds a delirious Cloud from the Sector 7 Slums train station and is startled . Cloud snaps out of his stupor and recognizes Tifa . Though the reunion of the childhood friends is joyous , Tifa notes a strangeness in him , as Cloud claims they last saw each other five years ago , whereas Tifa knows it to be longer than that . To keep an eye on him and to discover the reason behind Cloud ' s inconsistent memories , Tifa convinces Cloud to stay with the eco - terrorist group AVALANCHE that she is also a member , whose hideout is at the Sector 7 Slums . In December AVALANCHE , along with their newly hired mercenary – Cloud – bomb Sector 1 Reactor and retreat to the Sector 7 Slums to avoid capture by the Shinra Electric Power Company . Cloud and Tifa reminisce about the promise Cloud made to her before he left their hometown of Nibelheim , and Tifa convinces him to fight alongside AVALANCHE . The next morning Cloud can spend time shopping in slums ' shop s before heading out to attack the Sector 5 Reactor . Shinra finds , through Don Corneo ' s assistance , the location of AVALANCHE ' s base , and decides to crush the terrorists by dropping the plate upon Sector 7 . AVALANCHE fights for the pillar that sustains the plate , but cannot save Sector 7 . The town is destroyed , killing the entire population of both parts of the sector , and the AVALANCHE members Biggs , Wedge , and Jessie , while Cloud , Tifa , and Barret Wallace escape . Denzel is one of the few to survive the destruction , having lived on the upper Plate of Sector 7 with his family , but is orphaned . Together with other orphans he joined in a band called Triple S , and made a living by selling scrap metal from the ruins of Sector 7 to the builders of the new city of Edge . Three years later in 0010 Vincent Valentine goes through the ruins of Sector 7 during the Battle of Midgar . Dummied content . In " Final Fantasy VII " Sector 7 Slums contain a lot of dummied dialogue that can only be accessed by hacking into the game data . Originally the scenes at Sector 7 contained more interaction between the AVALANCHE members and Cloud , references to Sephiroth , and even a glimpse of him via dream sequences , signs of Cloud ' s mental instability , and allusions to the nature of Materia . One well - known hidden scene is where Tifa and Cloud talk outside 7th Heaven bar , Cloud vowing he is leaving AVALANCHE to settle the score with Sephiroth for what he did to Nibelheim , and Tifa being surprised Cloud knows so much about the incident . In the final game the scenes are shorter and leave out a lot of exposition and plot elements , to be introduced later in the game . Locations . Sector 7 Slums Station . To Train Graveyard - North .
