Siolo Ur Manka
this Twi'lke Jedi Master left Corusant for the Jentares System more than seventy years before the Battle of Naboo, in an effort to separate himself from the rest of the galaxy and meditate on the Force. During the time he spent at the Jedi Temple, he was considered among the best Jedi warriors of the time. However, just before leaving for Jentares, Siolo Ur Manka renounced his lightsaber and set out to contemplate a purer technique. Darth Sidious ordered his apprentice, Darth Maul, to assassinate Siolo Ur Manka, but the Twi'lek managed to disarm Darth Maul with little more than a wooden stick. It was rumored that this defeat caused Maul to develop his two-bladed lightsaber, since the single-bladed weapon he had used against Siolo Ur Manka had been ineffective. Rather than creating a single weapon, though, Maul welded two lightsabers together at the base, creating a weapon with the element of surprise. Maul returned to the Jentares System shortly afterward, to complete his mission. When Siolo Ur Manka again bested Maul in combat, the Sith apprentice activated the second blade and killed the Twi'lek. Darth Sidious was impressed with Maul's skills and his creation of the two-bladed lightsaber.
