The Ab'Bshingh civil war was a centuries-long war between the Waroot and Farang species of Ab'Bshingh.
Behind the scenes
When the planet was discovered by the Galactic Empire, the many battles were studied by the Imperial strategist Crat Dakerno, who was sent to subjugate the two races sometime between 19 BBY and 0 BBY. Dakerno used their complex maneuvers to create the board game known as B'shingh.
