The Nercathi clan, a Twi'lek lineage originating on Ryloth, had roots extending back to at least the Dark Age of the Galactic Republic. One notable figure within the clan was Newar Forrth, a Jedi Lord who served as Ryloth's guardian during the New Sith Wars. After Forrth's passing, the clan's members fashioned three exquisite crystallite skulls as a tribute to the Lord. These skulls symbolized the core Twi'leki principles: Jasshi'rr, Waala, and Keysshi. The clan persevered through the Republic's decline and the Galactic Empire's ascent, only to be targeted by Imperial slavers during the Galactic Civil War. In an effort to halt these persistent raids, the clan formed an alliance with the Rebel Alliance, providing essential soldiers in exchange for armaments and safeguarding.
