Count Dooku's palace, also known as Dooku's Palace, was a fortified palace located on the planet of Serenno and was the home of the Sith Lord and Separatist Head of State, Count Dooku. This place was protected by battle droids.
ExteriorDooku's palace stood on its own grounds, a rectangular area located on a cliff face. Upon arrival, visitors would take the long, paved walkway that led to the keep and was flanked at either side by three ornamental gardens. In front of the building's main entrance was a double line of obelisks. The main tower contained the Count's quarters. It also featured a grand window on cliff side.
InteriorCount Dooku's palace was lavishly decorated with many statues and elaborate paintings. His private quarters were made up of luxurious furnishings. The palace also had various droids to tend to the Count and his guests.
During the Clone Wars, Asajj Ventress, along with two Nightsisters, launched an assassination attempt on the Count while he was sleeping. However, it failed and the palace sustained damage in the process. Mother Talzin then brought Savage Opress to the palace to become Dooku's new apprentice. Dooku taught Savage that his anger gave him strength and that he must feed off it to succeed. He then sent him on a mission to Toydaria to capture King Katuunko.
Later on, mastermind Moralo Eval constructed the Box in the palace for training bounty hunters, in order to kidnap Supreme Chancellor Sheev Palpatine.
Later Dooku summoned General Grievous to Serenno and ordered him to kill Ventress and the Nightsisters on Dathomir. Mother Talzin attempted to kill Dooku while he was in his base, which caused him terrible agony, but he contacted Grievous via comlink and ordered that he kill Talzin and follow the green mist which would take him to her. Dooku was saved by Grievous at the last moment. He then believed that the Nightsisters were destroyed so he redirected his attention to Savage Opress, his former apprentice. He summoned Grievous to his base and told him that he could sense that Opress was growing stronger each day. Although Grievous dismissed the fact that Savage could be considered a threat, Dooku said he was a threat to all people including themselves and that something sinister was rising.
