The technical hub, situated deep within the Jedi Temple on Coruscant, served as the central control point. Staffed by members from the Jedi Order's Technical division, the equipment within this chamber regulated the entire Temple's electrical grid, water supply, and air conditioning. Smaller auxiliary locations, like repair shops and switching stations, were scattered throughout the Temple, with a high concentration in the southwest part of the building.
Established during the Jedi Temple's renovations prior to 1000 BBY, the complex's technical hub provided control over the entire building's electricity, water, and atmosphere. The chamber afforded entry to numerous utility tunnels and the main power generators for the building.
During an incident at the Jedi Temple involving robberies and vandalism in 44 BBY, the technician Miro Daroon was in command of the technical hub, and therefore was tasked with removing the bugs installed by the Dark Jedi Xanatos. Unable to remove them through normal means, Daroon was forced to shut down all of the Temple's systems for twelve minutes to fix the problems. However, Xanatos had set the Temple to explode when the systems restarted, which would have destroyed the Order. Master Qui-Gon Jinn and his Padawan, Obi-Wan Kenobi were able to stop this by taking the Healing Crystals of Fire, the stolen power source of the planned explosion, from the fusion furnace, and ending the crisis.
More than ten years later, Padawans Anakin Skywalker and Tru Veld encountered one another while scavenging for a part in the Coruscant underworld that the technical hub was missing. Veld was seeking the part to help Master Ali-Alann repair his new nursery droid, while Skywalker wanted to use it for himself. Feeling remorseful, Skywalker gave the device to Veld, and they both returned to the Temple.
At the end of the Clone Wars, a three year-long conflict, Darth Sidious, the Dark Lord of the Sith, in his public persona as Supreme Chancellor Palpatine, gave the order to seize the Jedi Temple and murder all of its occupants. The Grand Army of the Republic overran the Temple, leading to extensive damage due to a massive fire that spread throughout its corridors. After the fire was extinguished, the Temple was abandoned, except for a small occupying force of stormtroopers.
Shortly after its abandonment, former Jedi Ferus Olin and the street urchin Trever Flume broke into the Temple to locate and destroy the rumored Jedi Prison. Entering through the damaged Tower of Reconciliation, the pair made their way to the Droid Repair Center, an auxiliary location of the technical hub. While searching through the debris for the old service tunnel entrance, the two intruders were discovered by a squad of troopers guarding the Temple. They quickly hid beneath the burnt remains of dead droids and, thanks to the timely scurrying of a startled meer rat, the stormtroopers dismissed the disturbance and moved on. Olin and Flume then quickly searched the Temple, determined that there was no prison, and fled in search of the elusive Jedi Master Fy-Tor-Ana.
Later, the pair came back to the Temple with Master Ana and found that High Inquisitor Malorum planned to destroy the Temple by overloading the main power core. Olin rushed to the chamber and quickly disarmed the bomb by reducing the power and draining the core of its energy. The Inquisitor's plot failed, and the Temple survived for another two decades, through much of the Galactic Civil War and the Galactic Empire's withdrawal from Coruscant.
The circular technical hub of the Jedi Temple housed all the main operating system controls for the entire building, while smaller auxiliary facilities maintained services in specific areas. Situated on the same floor as the Halls of Healing, the Tech Center was connected to the Temple's main service corridors and also had a passage into the main reactor. Along the curved walls were datascreens that constantly displayed updates from each of the Temple's systems. Monitored by the tech specialist on duty, the chamber was vital to the building's operation. The room had four exits: the main entrance, the entry to the service hall network, a heavy durasteel door leading into the central core, and the well access gate. Beyond the door marked "Fusion Furnace" was a small, circular chamber surrounded by a catwalk. In the center of the catwalk was an opening with a ladder that descended ten stories into the Temple's infrastructure. At the bottom of the ladder, the walls were lined with compartments and switches, each labeled with its function. Also located off this chamber was the white room, which contained the sublight generator and its control computer.
Near the base of the Tower of Reconciliation was a small droid repair center. Here, Jedi technicians repaired and upgraded the many droids that operated within the building. A durasteel shelf ran along one wall, holding parts and tools; while powered-down protocol droids lined another. A service tunnel with a wide entrance was located here; droids were transported down the white, low-ceiling, rounded corridor to other areas throughout the Temple.
After the Temple was abandoned, Ferus Olin explored this room, searching for the service hallway that led to the accommodation sector. The shelves and the droids had fused together from the heat of blaster fire, and the stone ceiling had collapsed, allowing rainwater to enter. Olin cleared the path to the service hall, narrowly escaping a patrol of stormtroopers.
