Fu'ulanh functioned as a transport ship for the Yuuzhan Vong. The ship's purpose was to carry members of both the Shaper caste and the Order of Yun-Yuuzhan to the planet Borleias, with the ultimate goal of transforming the world into a sanctuary for the Priests dedicated to Yun-Yuuzhan. In reality, however, Warmaster Tsavong Lah secretly planned for it to be the execution site of Priest Takhaff Uul and Master Shaper Ghithra Dal, along with their accomplices, all of whom had undermined the Warmaster by sabotaging his radank claw-arm. Lah had four rancors concealed within the Fu'ulanh, and he used them to devour the thirty individuals who had conspired against him. He then intended to deceive the Shaper and Priest castes by claiming that New Republic fighters had obliterated the vessel upon its arrival at Borleias. It is believed that the Fu'ulanh met its end sometime after these events.
