Yoda, a member of the Sith species, began his training from Darth Vader when he was three years old. When he was ten years old, he met a girl named Megan and fell in love with her, causing him to fall to the dark side of the Force. At that point, he moved to Nar Shaddaa where he found a pool of lava. Shortly thereafter, he captured Darth Sidious and many other Jedi and made them suffer and die within the pool of lava. He was then named the Sith Lord of Pain.
