Darth Zannah

When the Dark Lords of Kaan's Brotherhood of Darkness unleashed a planet wide Force storm during the Sixth Battle of Ruusan, Rain survived by instinctively enveloping herself and Laa with a bubble with the Force. Unfortunately, when she watched Laa being killed haplessly by Jedi scouts, she was so stricken with anger that she killed them, unwittingly giving in to the dark side to do so. Rain's display of rage attracted the attention of the war's only surviving Dark Lord, Darth Bane, who decided to take the young girl as the first and only apprentice in his fledgling Order of the Sith Lords. Rain cast away the handle of her youth, and became Darth Zannah.
