A-13 Ember was an Alpha-Class ARC commander of the Grand Army of the Republic during the Clone Wars, the Galaxy-wide war between the Republic and the Confederacy of Independent Systems. Ember was in command of Blue Talon Legion and later the 5th Elite Sector Army. His Jedi Generals were Kaja Tallan and the Togruta, Adhektara Valena. Ember was a motivated, strong, determined and honest soldier, though he had an emotional side to him as well, especially concerning the choice of duty or those he cared about. This hampered his ability to follow orders in his life, eventually causing him to disobey Order 66 and save his Jedi Generals from his men, even killing a lot of them before escaping.
He would later serve as a commander in the Old Republic Resurgence Army, a group of Jedi, clone deserters, former Separatist soldiers, senators, Republic senators, smugglers and volunteers of all sorts of species.
