Serenno was a planet in the Outer Rim Territories. It was known for its aristocratic Counts, the most famous of them being Dooku.


One thousand years before the Battle of Yavin it was governed by the six Great Houses to which the Counts of Serenno belonged; the Counts were amongst the wealthiest beings in the galaxy and believed in noblesse oblige and self-reliance. Two of the six Great Houses were Nalju and Demici. Other lesser noble families allied themselves with the Six or were distant relatives. Serenno capital backed many projects of the Galactic Republic of which the planet was a valued member, despite being a frequent hotbed of sedition. The planet was inhabited since at least c. 1,049 BBY, when Hetton was born on the world.

In 990 BBY, the planet was the site of anti-Republic agitation, and a failed kidnapping attempt of former Supreme Chancellor Tarsus Valorum, both of which failed due to the manipulations of Darth Zannah. Since the kidnapping attempt involved killing servants and attacking a guest under the protection of Count Nalju, it offended the Great Houses, which quickly took steps to eliminate the seditious movements.

Nearly a millennium later, Serenno gave rise to a far more dangerous rebel demagogue. Dooku was born on Serenno in 102 BBY. His family bore the title of Count and lived in a great house with rose bushes. Dooku once visited the seashell-littered shores of a Serenno ocean as a child.

After resigning from the Jedi Order in the aftermath of the Battle of Galidraan, Dooku returned to Serenno and resumed his hereditary title as Count, giving him control of the vast fortune controlled by his family. The planet acted as one of his strongholds during the Clone Wars. After murdering Jedi Master Sifo-Dyas, Dooku stored his cryogenically frozen body on the planet, to be retrieved several years later for transportation to Geonosis, where a blood transfusion between the dead Jedi and Qymaen jai Sheelal occurred. As the Clone Wars progressed, Dooku kept his castle on Serenno and used it as a base of operations from time to time. On one occasion, Darth Sidious contacted Dooku in his palace via hologram and ordered him to kill his apprentice Asajj Ventress, who was growing too powerful and posed a threat to the Sith. Ventress survived, and in retaliation, she led a couple of her Dathomiri Nightsisters to raid Dooku's palace and kill him. Despite their concealment power, Ventress and her two allies were no match for Dooku, who used the Force to hurl the three assailants out of the palace, a fall from which they barely survived.
