Within the Galactic Senate Building on Coruscant, the galactic capital, Senate Tier 125 functioned as one of the various levels comprising the main Senate Chamber.
Its distinction lay in housing the primary control panel for the chamber's 1,024 Senate repulsorpods, utilized by Senators, their aides and guards.
In 24 BBY, prior to the Clone Wars, Granta Omega and [Jenna Zan Arbor](/article/jenna_zan_arbor], galactic criminals, launched a significant operation against the Republic. Their target encompassed hundreds of Senators, their advisors, and Senatorial aides, alongside their primary objective, Supreme Chancellor Palpatine, in a large assassination attempt within the Senate Building's Grand Convocation Chamber.
Omega's programmed seeker droids, numbering in the hundreds, possessed crucial data pertaining to key Senators and Palpatine. The Senate chamber quickly devolved into chaos, "filled with shouts and screams, the smoke of blasters, and the unmistakable smell of fear." As the assault unfolded, Obi-Wan Kenobi, a Jedi Knight from the Jedi Order who had rushed to defend the Senate, swiftly recognized that the Jedi required an advantage to protect the thousands present, given the droids' aerial superiority. Serendipitously, Kenobi discovered a terrified Senatorial assistant concealed within the luxurious draperies of a pod from Belazura, still connected to its docking station. Kenobi inquired about the location of the main pod controls. Prompted by the resolute tone in Obi-Wan's voice, the hesitant assistant promptly allowed him to board and demonstrated the central repulsorpod controls (which could override all individual pod controls), located on a wall panel within Senate Tier 125, by dropping the pod 10 levels. Manipulating several diagram indicators, Kenobi arranged the pods into a schematic, forming substantial blocs with a stepping-stone effect throughout the Senate chamber. Instructing the trembling aide to remain in place for safety, Obi-Wan hurried back to the tier entrance, where he observed the success of his actions. With increased airspace coverage, the Jedi were leaping from pod to pod, systematically reducing the number of droids targeting the terrified Senators. Reinforcements from the Temple, including Shaak Ti and Coleman Trebor, were now surging onto the Senate floor. The Jedi observed that the momentum had shifted.
