"I can hear them…Dooku…Dooku…"
Sifo-Dyas, seeing the future of Serenno[3]

Serenno was a planet located in the Outer Rim Territories' D'Astan sector, covered in lush forests, mountains and plains. Serenno was named after its ruling family, House Serenno. During the Clone Wars, it was aligned with the Confederacy of Independent Systems, the leader of which was the Serenno-born Count Dooku.


Serenno was a terrestrial[5] planet located in the D'Astan sector's Serenno system, in the Northern Dependencies[2] of the Outer Rim Territories, in grid square P-5 on the Standard Galactic Grid.[1] The planet sat a prime point along a maze of key hyperspace lanes, close to the planet Toprawa and the Corporate Sector that lay to the northeast, at the very start of the Hydian Way super-hyperroute. To the east sat the vast Gordian Reach and, within it, the Yavin system, while Mandalorian space lay south. A direct route down the Hydian Way to Brentaal IV would mean a short jump across to the planet Coruscant and the galactic seat of power. It was also situated along the Spurs of Celanon.[2]

Serenno orbited a singular star[2] and was orbited by two moons, including the moon of Mantero.[3] Its surface was covered in lush rainforests and mountain ranges, as well as savannas, which gave way to rivers that spilled into oceans.[2] Serenno silver was a type of metal that shared its name with the world.[11] The plains of the world hid seams of sacanium that were discovered during the invasion of Serenno.[3] The capital city of Serenno was Carannia, which was a town with vaulted structures and cylindrical towers that extended to the forest-covered hills of the mountain range nearby. The city housed the Carannia Spaceport, as well as the Great Assembly House, which was an arched building that hosted Serenno's Planetary Council.[8]


"And for your information, I am the boss. I am Duke Solha of the Free System of Serenno."
―Solha, to Anakin Skywalker and Thrawn[9]

According to the legends of the noble houses of the planet, Serenno was once a planet under the control of the Sith Empire. The eight great houses were mobilized by the House Serenno and, according to their histories, expelled the Sith forces without Jedi assistance. As a result the planet was subsequently renamed in honor of Serenno, member of the house. Later, he formed the Planetary Council and joined the Galactic Republic.[3]

Around 232 BBY[12] during the High Republic Era, the planet was represented in the Galactic Republic by Senator Izzet Noor, who was also the spokesperson for the majority of Outer Rim locations that had been brought under the Republic's control.[13]

By 102 BBY,[source?] Serenno was ruled by Count Gora. Shortly after the birth of his second son, Dooku, Gora realized that the boy was Force-sensitive; due to his hatred of them Gora quickly contacted the Jedi Order and then left the boy alone in the forest outside of his palace to die or be found by the Jedi seekers. Gora subsequently refused to speak of Dooku. As such, his other two children, Ramil and Jenza, and the wider Serennian public were initially unaware of Dooku's existence. Gora's rule was unpopular for many Serennians due to him often laying off workers and replacing them with droids. The unrest even led to a protest in[3] 82 BBY[source?] at the Funeral of Countess Anya, during which Gora almost ordered his Security Droids to fire on the protestors until Dooku intervened. This intervention unwittingly revealing Dooku's identity as Gora's son to the Serennian public.[3]

After becoming Count, a title he took on after the invasion of Serenno,[3] Dooku founded the Confederacy of Independent Systems, an alliance of solar systems who wanted to secede from the Republic, he moved his headquarters to a cliff-side castle on Serenno.[5]

Around 23 BBY,[14], in the great hall of his castle, Dooku tasked Asajj Ventress to go and find his sister, Lady Jenza. For her to find Jenza, she looked through datapads and Dooku's journal, and learned how Dooku was before he left the Jedi Order. She finds out that she had been kidnapped and would be tracking Glute, a Crolute criminal who was hired by Raz Fellidrone. Before Ventress could get information from Glute, a sudden blaster bolt was fired into Glute's head, shot by a Republic Intelligence officer, Raz Fellidrone. He tortured Jenza to try to get information out of her to help the Galactic Republic. Ventress caught up with him and stabbed him through his chest with her lightsaber in his apartment on Serenno. Dooku really intended for Jenza to be killed, for the information she held, as Ventress was later ordered. She then said "I'm sorry" as she buried her lightsaber into Jenza's chest.[3]

The hostility between the Republic and the Confederacy turned into a pan-galactic conflict known as the Clone Wars, and Serenno became a stronghold of the Confederacy. Protected by a cordon of Confederate warships, the planet was kept insulated from the worst of the Clone Wars battles.[5]

At some point, the Sith Master of Dooku, Darth Sidious, contacted Dooku in his palace via hologram and ordered the count to get rid of his pupil, a Dathomirian named Asajj Ventress. As Ventress had grown too powerful, Sidious feared that she would pose a threat to his own plans. However, Ventress survived Dooku's attempt to kill her. After returning to her people on Dathomir, she came back to Serenno with her fellow Nightsisters Karis and Naa'leth to raid Dooku's palace and exact revenge on him. Nevertheless, the Nightsisters were no match for the count, who used the Force and hurled the intruders out of the palace. After the skirmish, Dooku received a transmission from the Nightsister Mother Talzin, who offered to replace Ventress with Savage Opress, a Dathomirian Nightbrother.[6] Upon completion of the deal, Opress was delivered to Dooku on Serenno,[15] and the count started to train him on that planet.[16]

Some time later, Dooku summoned eleven of the galaxy's best bounty hunters, which included Cad Bane and Rako Hardeen, secretly Obi-Wan Kenobi in disguise, to his home planet. He wanted to recruit the best suited candidate to take part in Moralo Eval's plot to abduct the Supreme Chancellor of the Galactic Republic. In order to do so, Dooku then put the bounty hunters in Eval's Box, a cubical structure hosted on Serenno.[17]

Towards the end of the Clone Wars, Dooku imprisoned the Jedi assassin Master Quinlan Vos at his palace on Serenno. There, the Sith Lord subjected the Jedi to prolonged periods of torture. In order to push him to the dark side, Dooku revealed that his fellow assassin Ventress had murdered Vos' late Master Tholme. Enraged, Vos embraced the dark side and became Dooku's latest apprentice. When Ventress arrived with Boba Fett's syndicate to rescue Vos, he spurned their rescue and sided with Dooku.[18]

The main events of The High Republic: Light of the Jedi occur several weeks before the dedication of the Starlight Beacon, which The Star Wars Book dates to 232 years before the events of Star Wars: Episode IV A New Hope. Since Star Wars: Galactic Atlas dates the events of that film to 0 BBY, it can be determined that the main events of Light of the Jedi occur around the year 232 BBY.

  14. Star Wars: The Clone Wars: Character Encyclopedia - Join the Battle! places the recruitment of Asajj Ventress as Dooku's assassin to 23 years before the events of Star Wars: Episode IV A New Hope. As Star Wars: Galactic Atlas states that A New Hope begins in 0 BBY, Ventress' recruitment must have occurred in 23 BBY. As Dooku: Jedi Lost takes place after Dooku recruited Ventress, the mission must have occured around 23 BBY.
