Nilrebmah II was a planetary body located within the Nilrebmah system. This planet possessed an atmosphere composed primarily of fluorine. Its surface, largely composed of desert landscapes, exhibited significant cratering, a consequence of frequent asteroid impacts caused by the abundance of asteroids present within its atmosphere. It served as the homeworld for a civilization that remains unidentified to this day.
At some point in the Old Republic era, the Jedi Knight turned fallen, Ku'ar Danar, orchestrated an experiment within the Nilrebmah system. As part of this experiment, he brought the civilization residing on Nilrebmah II under his control, compelling them to construct a massive monolith on Nilrebmah XIII. The construction involved the use of living, Force-sensitive stones sourced from Nilrebmah X, with the ultimate goal of utilizing the Force to relocate an entire planet from its established orbit.
