First duel on unidentified desert moon

The Duel on Aridus was a lightsaber duel fought between Jedi Shadow Celeste Morne and the Sith Lord Darth Vader on the planet Aridus.

Prelude
Determined to get rid of the infamous "Jebble Box", the crew of the Uhumele comes to Aridus to give it to Fane Peturri, a well known scholar and historian. Unfortunately, Peturri was one of Darth Vader's agents, who learned of the ship's cargo from Janks. After having the crew cuffed to poles, Peturri began looking through a holographic message left by a Snivvian crimelord, detailing his "memoirs", the Muur Talisman, Jebble and rakghouls, which is interrupted by his Jedi friend.

Opening the box
Against Peturri's warnings about the Talisman, Vader slashes open the crate holding Dreypa's Oubliette and opens it, finding a young woman, Celeste Morne, inside, with the Muur Talisman attached to her neck. In a panic, Peturri puts on a helmet to keep from getting infected. she wakes up, expecting to see Zayne Carrick, but still felt the spirit of Karness Muur alongside her. Muur cursed his enemy Dreypa and his oubliette. Confused, Celeste asks Peturri about a Covenant, the rakghouls, the Mandalorians, their conquest and the Republic. Peturri informed her that the Sith overthrew the Republic, causing her to attack Vader. The latter taunted her to give in to the dark side.
