Xaart's mission was far more important to the fate of the galaxy than was first realized by Surik; he determined that if Onderon were to successfully secede from the Republic, enough surrounding systems would join with it, eventually spelling the doom of the Republic.

Although he had become stranded on the planet after the wars, Surik helped him to obtain a visa in order to travel back to his homeworld.
