The ghosts no longer pay any real attention to you, circling around one another. That they would try to spar one another while both are immaterial would probably seem odd to anyone benefitting from looking at this from a distance.
"I grow tired of your contempt and prideful arrogance, Jedi" The Sith calls out, ready to strike.
"It's not me that you need concern yourself with. I know the road to your salvation."
"You expect me in death to become what I fought against in life? A Jedi, Like you? Never."
"There is more to the galaxy than simple Jedi and Sith. Even in death, it is not too late. You can be at peace if you truly wish it. Forgiveness will succeed where vengeance has failed you."
The Sith, enraged by what he was hearing lunged at her, and a spirited fight began. Although he was the more fierce opponent, she was the more skilled, and even while on defense, was in control of the fight, as the two spirits moved about the cave. Despite their incorporeal nature, the blades of their phantom lightsabers still burned the walls and stalagmites where they struck the real world.
As you stare at the fight, trying desperately to stay out of the way, something pulls your attention away. A large stone near your feet is moving about, and is dislodged from underneath. Rolling away, you find the most curious thing underneath; a small tunnel, currently inhabited by a Jawa. Wix, no less
"Utinni! It's you! You find strange thing! Wix find you!" He scurries out to watch events beside you.
In attention on him, you missed the exact events between the two fighters, but the Sith's phantom lightsaber was cut in half, and he fell to his robotic knees in quiet shame. The Jedi sat across from him,
"Your life is marked by a viscous cycle. One of Hatred, Violence, and Failure. The path of forgiveness and peace has to begin inwards. The events of your life were never in your control, and you cannot blame yourself having been used as a pawn."
"I was deceived! Betrayed!"
"One of the countless he discarded along his way to gain power. There is nothing that can be done to change this. You must accept the events as they happened."
It seems as these world are finally beginning to sink in to the dead Sith. His breathing slows to a deliberate pace
"You must let go of the rage that has fueled you for so long. Be at peace with yourself, and with The Force."
"I'm ready." The Sith says simply, as his spirit begins to fade away, the last of Darth Maul having finally been put to rest. The Jedi disappeared as well, though her reassuring voice remained.
"Let this serve as a lesson to you. The past is vital to who we are, but do not let your past failures deny you of your future. The Force is with you both."
