The Conclave on Kessel was a meeting of Jedi survivors of Order 66. The Conclave was organized by Jedi Master Shadday Potkin and took place in an abandoned mining facility on the planet Kessel. According to official reports Lord Vader single handedly defeated more then fifty Jedi. The true list of fallen at Kessel (with their politcal leanings) includes:
Jastus Farr - rebuild Jedi Order by gathering scattered Jedi survivors and the remains of the Separatist armies (droid and sentient)
Koffi Arana - assassinate the Sith Lords
Ma'kis'shaalas - leave the explored galaxy permanently
Obi-Wan Kenobi - follow Yoda's instructions and go into hiding
Shadday Potkin - take direct action immediately
Sia-Lan Wezz (Padawan) - fight the Empire
Tsui Choi - join the rebelious Senators
