Kall distinguished himself in early Alliance fleet operations and organized several crucial logistical operations with privateers and raids on Imperial installations. He was a natural fit for a Special Forces command position and was one of the first General Cracken selected.
The investigation of Commander Kall's death during the final mission of the Liberation Day IV is currently underway. The current official conclusion of Coruscant Security Forces is that he was assassinated by a bomb placed by Imperial partisans in retaliation for his activities during the war. It is a tentative conclusion, for our purposes.
