Kalm (カーム, Kāmu?) is a village in Final Fantasy VII located outside of Midgar. Unlike the bustling metropolis nearby, Kalm is a quiet hamlet with only a few shops, a pub, and an inn. The economy is based upon mining in the Mythril Mine, but during the time of Final Fantasy VII due to recent activities of Midgar Zolom outside the mines, work has stopped.
During a military bombing operation, the target of which was supposed to be 50 kilometers north of Kalm, due to equipment malfunction the target is thought to be Kalm itself. The resulting destruction leads to an incident similar to Nibelheim Incident where the entire township is destroyed.
Survivors are shipped to the Shinra Mansion in Nibelheim, where they are thought to have died. The town is rebuilt, and the incident covered up. It is thought the survivors were executed to support the cover-up, but as many of them are test subjects to Professor Hojo's experiments in fusing Materia into human beings, it is more likely they were either mutated or killed due to the experimentation.
The sleepy village is the first town Cloud, Barret, Tifa, Aeris, and Red XIII come across after leaving Midgar. When the party stays at the inn, Cloud tells the tale of the incident with Sephiroth destroying Cloud and Tifa's home town of Nibelheim several years ago. Once the story ends, the party leaves.
Later on Marlene is sent to Kalm to escape the Shinra Electric Power Company. Despite the town's proximity to Midgar, it is not destroyed when Meteor falls. Marlene views the destruction and saving of the Planet by the Lifestream and Holy from Kalm.
Following Meteorfall and the destruction of Midgar, there were many people who traveled to the town to take refuge. Residential houses became emergency shelters and the inn offered free rooms to refugees but the sheer volume of refugees forced some people to live on the streets. The near-immediate introduction of a new disease that began to plague the populace did not help matters.
Under the threat of death from an unhappy public blaming the Shinra Electric Power Company for Meteorfall, Rufus Shinra, now residing in Kalm, concocted a plan to redirect the populace's energies toward rebuilding their homes, using the wreckage from Midgar and build a new town on the eastern-side of Midgar.
One year after the events surrounding Kadaj and Sephiroth's return, and three weeks after the disappearance of an investigative team of more than 38 people into a previously sealed section of the Midgar ruins, Kalm comes under attack by an unknown military force during a night-time festival celebrating the recovery from Meteorfall.
Targeting individuals who had not been infected by Geostigma for capture, Vincent Valentine, who was residing in the town at the time of the festival to meet with Reeve Tuesti, disrupts the raid and supports the World Regenesis Organization in pushing the mysterious army out of Kalm, but not before he encounters the Tsviets Azul the Cerulean and Shelke the Transparent.
Cait Sith later comes upon some citizens from Kalm within Reactor 0 underneath Midgar, captured during Deepground's raid and still contained within the Dragonfly equipment containers, and watches helplessly as they are sacrificed enmasse to awaken Omega.
- Village Square
The party enter the village square from the south-west corner. The Inn, shops, and various residences can be accessed from here.
The Inn is located to the left of the village entrance, and visiting it is essential to move the story forward. It is here that Cloud recounts his experiences as a member of SOLDIER to the party.
There are four residences in total, all containing various treasures. The central house of the three beside the Inn is notable for its locked chest on the second floor, that has no means of opening. This chest had originally contained the Titan materia, but the idea was scrapped and the materia was moved to Gongaga instead.
Located through a tunnel beneath the upper level of the village, the pub is frequented by miners who are out of work due to the Midgar Zolom.
There are three shops located on the upper level of the village, where the player can purchase materia and mythril-based weapons and armor.
