Impel Down Rumble JUS

Impel Down, also known as the Underwater Prison and the Great Prison , is a government-controlled stronghold in Paradise together with Marine Headquarters and Enies Lobby. It is the World Government’s maximum-security prison for the most dangerous criminals and pirates. It is located underwater in the middle of the Calm Belt and part of the Tarai Current. Impel Down is the main setting of the Impel Down Arc, with the prison’s staff acting as the main antagonist group in the same arc.

Impel Down is a large, submerged tower-like structure whose foundation is at the very bottom of the sea bed. Due to it being built within the Calm Belt, the entire structure is constantly surrounded by gigantic Sea Kings swimming below the water. Along with these beasts, the prison is guarded by a force of Marine battleships.

Within the dark confines of the prison are various cells and torture chambers that are used for the prisoners. The cells are all made from Seastone to keep those with Devil Fruit powers from escaping. The torture chambers are used for all sorts of brutal, unspeakable acts. Among these include continuous whipping, brutal beating to death, boiling cauldrons for burning and drowning, and spiked pits used for impaling.
