Obi-Wan Kenobi has left the Jedi Order because of a civil war on the planet of Melida/Daan. He's now part of the Young faction but is content with his decision. However, soon everything goes wrong. Once the Young unite the two major factions, they start to fight among themselves. In the crossfire, Obi-Wan's close friend, Cerasi, is killed and Obi-Wan feels alone.
Meanwhile, Qui-Gon Jinn, Obi-Wan's former Jedi master, discovers a plot to destroy the Jedi Temple. While investigating, he receives notice that Obi-Wan wishes to rejoin the order. Qui-Gon knows that Obi-Wan would be an asset to the investigation at the temple so he decides to return and bring his ex-apprentice back to the Jedi Order.
The Young cease their internal struggle and succeed in uniting the Melida and the Daan factions under one government. With his task complete, Obi-Wan returns to the Jedi on Qui-Gon's return. However, he is not immediately welcomed with open arms for the Temple plot thickens when an assassination attempt is made on Yoda.
