Darth Vader was seen walking across the Supplicants Waiting Hall
The Supplicants Waiting Hall functioned as an antechamber, situated just outside the Imperial Palace's throne room of Emperor Palpatine on Coruscant. In this lengthy corridor, individuals awaiting an audience with the Emperor assembled, remaining there until the moment the Emperor was prepared to receive them. The hall featured stone columns lining its length, punctuated by the presence of windows between them.
