anakin's children, leia, and luke skywalker would become key members of the rebel alliance to restore the galactic republic. luke would be secretly tutored in the ways of the force by vader's own former jedi master, obi-wan kenobi, and a powerful elder jedi, yoda, who also survived palpatine's purge. ironically, during a final confrontation between luke skywalker, darth vader and the emperor aboard a mobile battle station known as the death star, the sith lineage would end as darth bane prescribed that it proceed. darth sidious offered skywalker an ultimatum to enter his service or die, and proceeded to use his force-derived powers to torture and kill skywalker when the latter refused to embrace the dark side of the force. experiencing a crisis of conscience at the imminent death of skywalker, whom vader now knew to be his son, darth vader chose to intervene and kill his former master, sidious fulfilling the prophecy of the chosen one. vader would die of his own injuries shortly thereafter, thus apparently bringing an end to the sith and their ancient vendetta.
