As the war between the Confederacy of Independent Systems and the Republic went on, more and more of those in the Republic began to lose trust in the Jedi Order. In the most extreme cases, people found and researched ancient Sith texts, bringing about the beginnings of a new Sith Order. The Sith backed the Separatists, and began destablizing the Jedi further.
On Coruscant, Sith Assassins were everywhere. Public officials being killed in the streets became a daily occurence. The Senate feared these assassins so much, they placed an order for another 500,000 clones just for the Coruscant Guard. The Jedi Order began hunting down these assassins, you and your master were sent out to hunt the one known as 'Darth Panthera', but your master was called back to the Temple for more pressing issues. He trusted you to find the assassin on your own.
One night, you were standing outside of Dex's Diner when the assassin showed herself. She meant to kill another Senator, but a police robot got in the way. The Senator was alerted and ran, you ignited your lightsaber to fight her, but she ran off instead.
You chased her for at least twenty minutes before she ran into an alleyway and caught you off-guard. She held her lightsaber close to your neck and pushed you against the wall.
"Oh, c'mon, I ran for that long and I don't even get to kill a master? You're just a lowly knight... What're you doing out here alone?"
