Ngaaluh was a female Yuuzhan Vong deception sect priestess, and loyally worshiped the goddess Yun-Harla for much of her life. During the Yuuzhan Vong War, however, Ngaaluh had her belief in the True Way eroded by an interrogation subject; the Fosh Jedi Vergere. The priestess harbored her new heresy for some time, reaching her own conclusions and coming to believe strongly in the Force and the role it could play in her species' journey.
