Expedition to the tomb of Freedon Nadd

This is a quest from the videogame Star Wars: Knights of the Old Republic II: The Sith Lords. The Sith have allied themselves with General Vaklu of the Onderon Military, spurring his secessionist movement on in the hopes that the Republic would lose a pivotal planet and collapse irrevocably. Vaklu presses his advantage, but as the Jedi Exile tries to save Queen Talia on Onderon, three of her disciples set out to stop Sith forces on the nearby moon of Dxun, turning the tide of battle.
