The first mission to the Yinchorri system occurred in 33 BBY, during the Yinchorri Uprising.
After news of the Battle of Mayvitch 7 reached the Galactic Senate, Supreme Chancellor Finis Valorum requested that Mace Windu send a Jedi team to Yinchorr to negotiate. Without discussing it with the Jedi Council, Windu sent Jedi Knight Naeshahn and her Padawan, Ebor Taulk.
The two were unaware of the Yinchorri immunity to mind tricks, use of cortosis weaponry, or aggression. The Jedi were killed, their mutilated bodies later deposited upon Valorum's Coruscant doorstep.
