Serenno

Serenno was a planet covered in lush forests, mountains and plains. During the Clone Wars, it was aligned with the Confederacy of Independent Systems, the leader of which was the Serenno-born Count Dooku.

History
In the time of the Galactic Republic, Serenno was home to a noble house of which Count Dooku was a scion. Although Dooku had renounced his status to become a Jedi Knight, he ended up leaving the Jedi Order and came back to Serenno to reclaimed his wealth and territory. When Dooku founded the Confederacy of Independent Systems, a, he moved his headquarters to a cliff-side castle on Serenno. The hostility between the Republic and the Confederacy turned into a pan-galacticconflict known as the Clone Wars, and Serenno became a stronghold of the Confederacy. Thanks to a cordon of Confederal warships, the planet was kept insulated from the worst of the Clone Wars battles.

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 him to replace Ventress with Savage Opress, a Dathomirian Nightbrother. Upon completion of the deal, Opress was delivered to Dooku on Serenno, and the count started to train him on that planet.

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 Moral Eval 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.
