Star Wars: Jedi Apprentice, the Dark Rival

This story happened when master Qui-Gon Jinn and Obi-Wan Kenobi went to Bandomeer and he was awakened with a start. He had a nightmare of the past. But, he can't fight this power. They were quartered in the guest chamber of Bandomeer governor's official residence. Then Qui-Gon and Obi-Wan went to a meeting. Qui-Gon was surprised of who the representative of Offworld Corporation. It was Xanatos! Xanatos was one of Qui-Gon's Apprentice he was an apprentice before Obi-wan. Then the meeting followed as it was expected. Then suddenly a huge blast came from below the building and many died in the accident. Or shall we say....Incident. Everybody blamed Xanatos and Offworld Corporation. But he denied that it wasn't his fault. Then Qui- Gon was suspicious during the blast, he thinks that Xanatos wants him to be confused. It slowed him down, but he felt a disturbance in the force. So they decided to make a trip to Offworld Corporation Qui-gon and Obi-wan decided to split up. Qui-gon told Obi wan to stay here and don't wander. He didn't listen. After all, Qui-gon isn't his master yet he is still to be determined. Qui-gon hoped that Obi-wan won't discover that Xanatos was his Apprentice because Xanatos was tempted into the dark side and ran away. He swore revenge. And Kenobi saw a dark room and he knew there was somebody coming he hid there among the boxes hoping that he wasn't seen. Then the person saw Kenobi because of the force. It was Xanatos. Obi wan didn't know him so they talked until Xanatos brought up the topic that he was a student of qui-gon. Then, the guards came and it was a battle. Obi-wan got knocked down on the floor and the next thing he knew he was in a strange place. It was like a slave factory there were hundreds of them each wearing a funny-looking collar. Someone said that if he/she will escape, the collar will blow up. Obi-wan didn't know any solution except that if Qui-Gon will find him and rescue him. Then qui-Gon found him and he was ready to escape but the collar, it was the problem. Qui-Gon tried to brake it using the force. But he failed then they wandered off hopefully to find a remote that controls the collar. Then they met Xanatos and Xanatos pulled out his light saber and signaled qui-Gon to prepare for a duel. And so they dueled they countered every attack that they attacked. Qui-gon managed to kick Xanatos and it flew, the remote that controls the collars and obi-wan got it there
