Members of the Neti species possessed the ability to unleash a remarkable beam of light. This was achieved by channeling the totality of the Force energy from the planet they were connected to, or another significant energy source, at the time of their death. This immense power could result in catastrophic destruction of a planetary surface, and the complete annihilation of starships and other crafts. As an example, in 10 ABY, the venerable Jedi Master Ood Bnar discharged a ruinous beam of light to eliminate Executor Sedriss, thereby rescuing Jedi Knights Luke Skywalker and Kam Solusar.
Over one hundred years afterward, when Emperor Krayt's military achieved victory in their attack, a Neti Master, T'ra Saa, along with fellow Jedi Nat Skywalker, jointly emitted a beam of light. This beam was used to forge an escape path for their comrades, drawing directly upon the energy of the Temple's exploding reactor.
After the passing of both Bnar and Saa, tiny saplings sprouted from the earth at the locations where the Neti had perished. These saplings appeared to be filled with the planet's Force energy, which continued to move through the deeply rooted connections.
