"There were no survivors on Devaron. Everyone was killed, including Master Halsey and his Padawan."

Halsey was a male Roonan Jedi Master active during the Clone Wars. Later in the war, Halsey, along with his Nautolan Padawan Knox, was dispatched to the Temple of Eedit on the planet of Devaron to defend it from the Separatist Droid Army. Halsey and his Padawan were both killed at the temple by the Dathomirian Zabrak Savage Opress, Count Dooku's new apprentice.
