During one of these missions she would break the Jedi Code's rule of attachment by falling in love with Darman, RC-1136, a clone commando in Omega Squad, and becoming pregnant with his child, Venku Skirata. The two would later marry in the traditional Mandalorian way shortly before her death in 19 BBY.
In the original trilogy, Yoda lives in solitude on the swamp planet Dagobah. He is introduced as a former mentor of the Jedi Master Obi-Wan Kenobi, and he trains Luke Skywalker in the ways of the Force until his death at the age of 900.
