Yaddle (Earth-2042)

"Yaddle! The old being— The one below..."

- Three Kobans, on Yaddle

Yaddle, also known as the "One Below", was a renowned female Force-sensitive  Jedi Master of an unidentified species, who went on to serve the Jedi High Council for over a century before her death in 26 BBY during a peacekeeping mission to Mawan. A member of the same species as fellow Jedi  Yoda, but about half his age, Yaddle trained dozens of Padawans in her time as a Jedi Master, such as Oppo Rancisis, who would later join Yaddle on the High Council. After completing Rancisis' training, Yaddle did not take another apprentice, as she was almost five hundred years old when Oppo passed the Jedi Trials for Knighthood.
