In 5 ABY, he agreed to come to Dorlo to study an ancient three mile-long wall excavated there, which SoroSuub executives hoped contained lost technology. Jedi Master Qu Rahn came to Dorlo shortly thereafter to solicit Ral to join the Rebellion, which he reluctantly agreed to.
However, on their way off the planet, Jerec's Dark Jedi arrived and captured the Rebel team. They were taken to Jerec's Super Star Destroyer, Vengeance, and were forced to reveal the information of the Valley of the Jedi. When Rahn and his companions refused to reveal the location, Ral was executed by Yun who beheaded him with his lightsaber. Afterwards Yun experienced several nightmare's going over the event where Yun found himself executing Nij Por Ral again and again, ignoring Ral's pleas for mercy.
