Serenno was a male member of House Serenno. At some point during his life, the Serennian led a victorious charge against the Sith Empire which ruled over Serenno. Once their bondage to the Sith was broken, all of the family houses of Serenno gave House Serenno the honor of being the ruling house of the planet. He also formed the Planetary Council and joined the Galactic Republic. Among his descendants was Count Dooku, who, ironically, became a Sith Lord.
