Erangel is an island in our imaginations located in the Black Sea.
From around 1950, the island was occupied by the Soviet Union and used as an army installations.
As a result, you can find the Military base, a hospital and storage facilities.
People who were involved in the resistance movements from local self-governments tried to get their island back, but failed and the island was neglected.
The magnetic field was used to gain control over those people that were involved in resistance movements.
