The Dark Council meeting room, located on Vaiken Spacedock, served as a location for the Sith Empire throughout the third Galactic War. This room was a precise duplicate of the one utilized on Dromund Kaas in the era of Empress Acina's rule.
The Dark Council meeting room makes an appearance exclusively during the Onslaught expansion's storyline, and only if the player character's original class is aligned with the Empire.
Even though the Dark Council had its membership decreased to only 5 councilors, the room contains a total of twelve chairs, in addition to the Emperor's throne, with six chairs positioned on either side of the room.
Depending on the player's choice to side with the Empire on Iokath, Empress Acina would preside over the Dark Council assembly in the Onslaught expansion. If the player did not side with the Empire, Emperor Vowrawn would be the one to chair the meeting.
