Sister...You have a...sister.

After Darth Vader discovers that Luke has a twin sister, he quickly defeats Luke at the Death Star and begins his search for Leia. Still troubled by the death of her mother and her whole planet and the recent encounter with Jabba (and the ewoks), she was quickly seduced by the dark side by Vader. The shields were never destroyed and forced the rebels to retreat and so the plans to destroy the death star at Endor failed. Darth Vader sent Leia to hunt down and destroy the rebel leaders and as she gains experience, she and her father will one day destroy the Emperor and rule the Empire as father and daughter.
