The House Juoni referred to a family whose origins were on the planet of Kaikielius.
In the era of the Galactic Republic, the Juoni family held significance as an aristocratic power on Kaikielius. Alongside competing families House Praji and House Vahali, they formed the Triad, a group wielding substantial influence on Coruscant.
During the First Alsakan Conflict, occurring in 17,000 BBY, the Juoni expanded their influence into the Expansion Region and aligned themselves with Alsakan. Nevertheless, following Alsakan's defeat, the Juoni were divested of their holdings in the Expansion Region, and the leaders of the House were incarcerated at Centax-1 Maximum Correctional, located on Centax-1.
