The Capital of the Galactic Republic since 25,000 BBY, Coruscant is considered the most important political planet in the galaxy. From the Senate, the Supreme Chancellor coordinates with the Jedi Order in their long-lasting fight against the Imperial War Machine.
Known by many names, the Senate Tower was the literal center of Republic politics. Here the Senate would meet to discuss the various the finer points of Republic politics. The drum shaped building was at the end of the Avenue of Core Founders, a ceremonial pathway to the Great Door of the Senate.
Once the proud center of the Jedi Order, the Temple was destroyed in the infamous Sacking of Coruscant, effectively destroying the home and symbol of the Jedi within the Republic. The exterior of the Temple crumbled, the four stately towers falling upon the tiled roof, an empty ruin of its former self. However, much of the interior remained intact, symbolic of the Order's state of affairs following the attack. The reconstruction process was authorised by Supreme Chancellor Eidolon two decades later, but completion is expected to take quite some time.
The Ministry of Defense was the command and civilian oversight of the Republic Military Forces, headed by the Minister of Defense. The Ministry boasted its headquarters from within the Senate Tower, under the ever critical eyes of the Senate.
The Coruscant Underworld is rife with the scum of the Galaxy. Although not confined to Level 1313, the problem has become so widespread that the infamous layer has become synonymous with the entire Underground, and is used to refer to the underworld movement on all illegal activities on the subterranean levels.
