The Lorahns Cavity, a gravitational sink, presented a Class-3 navigational hazard on Vandor, the planet where it was located. This phenomenon made traversing the area around Vandor more difficult. It was named after Lorahns, an astronomical body situated in the Mid Rim Territories and sharing grid square P-14 on the Standard Galactic Grid with Vandor. Arhul Corubalni referenced it alongside the Lesser Sloo Gas Cloud within the planet's original survey documentation.
