The Paths of the Lost was a location on the planet Bajor. They were a series of catacombs that ran underneath the city and was where the Bajorans buried their dead which included some of the earliest of kais along with some vedeks as well as others that were revered for their faith. These underground tunnels were a labyrinth which seemed to extend for tessijens with knowledge of them being lost to the Bajorans for centuries to the point that they fell to legend. This meant that they wer not mapped and those that ventured too far into them ran the danger of never finding a way out.
