The Lowland Clans were one of the groupings of S'kytri clans that ruled the planet Skye. The Lowlanders and Highlanders combined made up of two-thirds of Skye's population. They inhabited the Lowlands region of Skye where they lived in mountaintop cities and citadels. The Lowland and Highland Clans took turns governing Skye by voting a member of their respective strata to the office of Patriarch every forty-two years. Many years prior to the Clone Wars, the Lowland Clans employed the Outland Clans as indentured servants. The Outlanders worked as serfs for the Lowlanders until all the clans eventually were able to rule over themselves and exist in relative peace and economic interdependence. At the beginning of the Clone Wars, the mad genetic terrorist Zeta Magnus arrived on Skye and transformed the Outlanders into a mutant army and turned them against the other clans. The Lowland Clans, dependent on the Outland Clans for agricultural products, began to decline due to starvation and attacks from the Outlanders. When a team of Jedi arrived to free Skye from Zeta Magnus, the Highland and Lowland Clans united to drive the scourge from their world. In the ensuing battle, the Lowlanders suffered an untold number of casualties.
