The Six Sisters consisted of six worlds in the Inner Rim, primarily inhabited by the Echani people, and governed by the female council known as the Echani Command. Among the Six Sisters were Eshan, the Echani's original home planet, along with Thyrsus and Begali.
In 1154 BBY, the Begali Uprising occurred when Thyrsus and Begali rebelled against the Echani Command. While Begali was reintegrated into the Echani Command before a century passed, the conflict between Thyrsus and Eshan persisted until the signing of the Pact of Almera in 899 BBY.
