Halsey

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

- Boss, reporting on the fate of Halsey

Halsey was a Roonan male Jedi Master active during the Clone Wars. At least one year into 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.
