Yaddle/Legends

Yaddle is a Jedi Consular who served on the Jedi Council during the events of Star Wars Episode I: The Phantom Menace - notable for being the only non-human female on the Council at the time. She is also notable for being the same species as the ancient and powerful Jedi Master Yoda, however neither's species has been officially revealed.

Yaddle herself is 477 years old during the events of Episode I, young compared to Yoda's ~900 years. She was known for her compassion and patience, as well as her mastery of the ancient and forbidden Jedi art of Morichro, a method for killing a being without using the Dark Side of the Force - a skill she taught to very few of her Padawans, due to its obvious capability for being misused.

Expanded Universe information
Almost three hundred years BBY, Yaddle was a padawan of the Jedi master Plovin Kut, when the two of them travelled to the Koba system to deal with the threat of a local warlord named Tulak. The two Jedi, however, were betrayed by spies and ambushed by the forces of the warlord, where Kut was killed and Yaddle was captured. Tulak then imprisoned the dimunative apprentice in a dungeon, far below the surface of the planet Koba. There Yaddle would stay for more than a century, honing her mastery of the Force, ready for her eventual chance to escape - which came when a massive earthquake struck, allowing her to escape to the surface. Instead of immediately returning to Coruscant, however, she remained on the planet and helped the Kobans rebuild their decimated society. These efforts attracted the attention of Tulak's heir, Kalut, who fought with Yaddle. Yaddle defeated the tyrant and in the process liberated the people of Koba once and for all.

When Yaddle eventually returned to Coruscant, the Jedi Council determined that her survival of a century of imprisonment and subsequent liberation of Koba were sufficient grounds not only to promote her instantly to the rank of full Jedi Master, but also to offer her a temporary seat on the Jedi Council. During this time, Yaddle trained dozens of Padawans, including Oppo Rancisis, a Thisspian who later also went on to serve on the Council. She was also a profficient healer and diplomat and went on many missions to mediate disputes.

Yaddle was killed in the Star Wars book Jedi Quest: The Moment of Truth, when she destroyed a chemical weapon, in the process saving the city of Naatan, but also dying instantly.
