• Tangrene is one of the more heavily defended planets in the Empire's sphere of influence, largely due to the presence of an Imperial Ubiqtorate base (which houses one of the few crystal gravfield trap arrays near the New Republic border). That General Garm Bel Iblis managed a successful raid against the planet is a monument to the Corellian senator's cunning.
  Tangrene is protected by a minimum of two Imperialclass Star Destroyers, and anywhere from 10 to 50 smaller vessels (ranging from Carrack-class light cruisers and Interdictor cruisers to Victory-class Star Destroyers). Imperial officers joke that anything that enters the system without authorization — including space debris — is destroyed without even so much as a comm warning. A complex series of remote sensors ensures that nothing gets into the system undetected.
  Tangrene itself is ideally suited to its role as an Imperial "fortress" world. Fifteen Imperial garrisons are scattered strategically throughout the cliffs and canyons of this nearly barren planet, positioned to take maximum advantage of the available terrain. Any attacking ground forces will be hard pressed to take and hold any of the planet's rocky ground.
  Tangrene was once home to a species of peaceful nomads that were enslaved by the Empire. They were forced to help construct the garrison bases and shield generators of the system's defense network. After construction was completed, the sector Moff decided it would be more expedient to depopulate the planet rather than risk revolt or insurrection. The Tangrene people were completely wiped out, without the slightest chance of defending themselves. Tangrene remains a monument to the Imperial capacity for cruelty.
  Tangrene is a craggy, mountainous world, almost completely devoid of surface vegetation and water. A number of underground lakes (and even one subterranean ocean) have been located and tapped to supply water to the Imperial garrisons. These underground caverns also support a wide diversity of fungi and vegetation. A number of glowing, fern-like lake plants help provide a breathable — if thin — atmosphere.
  The maze-like canyons that spread across the planet's surface have been mapped and secured by the Empire. Motion trackers, heat sensors and sentry observation posts monitor all access to the Imperial Garrisons and Ubiqtorate base.
  The Empire has recently upgraded the shield generators of Tangrene to make the planet even more difficult to penetrate. Because of Tangrene's position near the New Republic, the planet has become an increasingly attractive staging area for Imperial incursions into Republic space.
