Rhondi Tremaine was a Human female who was born on a colony in the Maw, and was a member of the Maw Irregular Fleet. With her brother Rolund Tremaine, they were used to gather information as spies. In 41 ABY, when Centerpoint Station was destroyed, both siblings felt a call through the Force to journey to Sinkhole Station, a scaled down version of Centerpoint. At Sinkhole, the two siblings joined the Mind Walkers, Force-sensitives that completely immersed themselves in the Force by separating their force auras from their physical bodies. In 43.5 ABY, exiled Jedi Grand Master Luke Skywalker and his son Ben boarded the station during their search to discover why Jacen Solo fell to the dark side.
