A possible depiction of the Senate Atrium, featuring statues and Jedi Master Orgus Din alongside lieutenant Tavus. The Atrium of the Senate functioned as the primary public area within the Senate Building. The Great Door of the Senate was situated at one end, while the Grand Convocation Chamber was accessible from the opposite end. Statues representing the most celebrated heroes and influential politicians of the Galactic Republic adorned its walls.
During the Yuuzhan Vong's capture of Coruscant during their invasion of the Galaxy, the Senate Building underwent a shaping process, transforming it into the Well of the World Brain. This was part of their larger effort to convert the galactic capital into the new world of Yuuzhan'tar. Despite these changes, the Atrium continued to serve as the building's main entryway, with yorik coral covering the walls, floors, and ceilings.
Following the World Brain's installation, a significant portion of the Atrium suffered destruction during Ganner Rhysode's momentous battle against the Yuuzhan Vong. However, by the time of the Battle of Yuuzhan'tar, which occurred a little over a year later, the damage appeared to have been concealed.
After Coruscant's liberation, the Atrium was restored to its original state and once again served as the Senate's main hall.
