“Ultra-Long Flight” is the name of the ship and its unprecedented mission. The mission was intended as a daring exploration expedition, but remains one of the darkest chapters in the history of the Republic. Several years before the Clone Wars break out, Jedi Master Jorus C'baoth asks the Senate for support in an ambitious endeavor. Six masters of the Jedi Order, twelve knights and fifty thousand colonists will set off on an expedition on a giant ship to establish contact with intelligent races and colonize yet undiscovered planets outside the Galaxy. Little does C'baoth suspect that this large-scale undertaking is not just supported by the Senate, but completely organized by the Sith Lord Darth Sidious, who has his own plans for the “Ultra-Long Flight”. And his plans do not include the safe return of the ship. However, Darth Sidious is not the most formidable danger looming over the expedition. On the edge of uncharted regions of space, the ship faces hostile forces led by a brilliant strategist known as Thrawn. Obi-Wan Kenobi, aboard the Outbound Flight with his young Padawan Anakin Skywalker, is unable to prevent disaster. And the journey that began as a peaceful research expedition turns into a brutal race for survival...
