The Obsidian Citadel is the seat of power of the New Sith Order. Located on Trandosha, the Obsidian Citadel is a towering citadel, a testament to the power of the Sith Order. The top level serves as the throne room for the Dark Lord of the Sith. It was constructed in 16 ABY as a place of worship for the followers of the Sith's false religion, but was soon turned into the Sith's capital building after the dismantling of the religion.
