Braindeath Island seems to have been formed by volcanic activity, and most scholars attribute this to the volcano that now stands dormant on the northern half of the island. The lack of igneous formations in the area suggests that it has not erupted for many years, but no one knows for how long it has been dormant.
Despite being dormant, the volcano plays an important role in the brewing of Braindeath 'rum'. The crater atop the volcano is now filled with stagnant water, marked by the water source icon (), which is used in the production of the 'rum'. Since the arrival of zombie protesters on the island, however, the bridge leading to the volcano has been barricaded and is guarded by 50% Luke.
