Hendri Underholt was a human woman who held the positions of archivist and aide under Mon Mothma within the Alliance to Restore the Republic. During 4 ABY, Mothma contemplated a journey to Durkteel, a world sympathetic to the Alliance, as a means of diverting the Galactic Empire's attention from an upcoming attack in the Endor system. Underholt voiced her opposition to this plan, arguing that Mothma's personal safety was too important to risk. She suggested that the deception would be equally effective if she, as Mothma's most trusted assistant, were to travel to Durkteel accompanied by bodyguards and a group of soldiers. Regrettably, the mission deviated from its intended course, resulting in Underholt's death when the Empire initiated a bombardment of Durkteel's Tak-Beam complex.
