Siolo Ur Manka

Siolo Ur Manka (in Twi'leki, Siolo'urmanka) was a male Twi'lek Jedi Master prior to the Battle of Naboo. He retired to an uninhabited jungle world to meditate, carrying with him only a staff, not a lightsabre. Darth Sidious sent Darth Maul to assassinate Siolo as a test. Using only his staff, Siolo easily deflected every single one of Maul's lightsabre attack. To solve the problem, Maul created his double-bladed lightsabre, and revealed its additional blade in his second battle with Siolo in a surprise attack that skewered Siolo from behind, ending the ancient Twi'lek's life.
