Fortress Inquisitorius (4)
1. Fortress Inquisitorius
A heavily armed underwater fortress concealed within the black seas on the shadowy world of Nur. The stronghold serves as the central seat of the Imperial Inquisitor Program, the Emperor's ruthless crusade to eradicate the Jedi Order from every corner of the galaxy. To maintain a public perception of peace and security, the existence of the fortress is intentionally hidden from the Empire at large, although rumors swirl of a "dark site" where Forceusers go to die... or worse.
Security Systems (4)
2. Submerged Section
Analysis of these pipes indicates that pressure buildup from an open airlock caused them to rupture. This breach could only have occurred if the shield system was compromised, rendering it unable to protect the Fortress from hydrostatic pressure. Data suggests the Fortress may be vulnerable to flooding if airlocks are opened while its shield system is disabled.
4. Control Room
Sectioned wings of the Fortress are designed for maximum security and stability in extreme undersea conditions. A complex system of partitions provides the ability to flood an entire wing or specific sector in response to any escape attempt by a high-value detainee. Structurally reinforced shielding is able to withstand an external breach or change in pressure at any depth.
