The confrontation on Kwannot was a lightsaber duel that involved Qui-Gon Jinn and his Padawan Obi-Wan Kenobi as they fought against the assassin Aurra Sing, the killer of Jedi Knight Mana Veridi. During this battle, the assassin managed to gain an advantage over the Jedi Master and his apprentice. However, Sing chose to escape, taking Veridi's lightsaber with her, after determining that the two Jedi were a greater challenge than she had originally thought.
Obi-Wan Kenobi later recounted this event in 0 BBY to the smuggler Han Solo while they were traveling to Alderaan on the Millennium Falcon. Kenobi explained to Solo that he preferred to think Sing ran because she felt outmatched by Jinn and Kenobi, though he admitted this was only his personal interpretation.
