Jahaal Aden was the oldest son to Kyr and Nasrey Aden. He became the standing chieftain of Clan Aden in late 18 ABY after Garen Starfall bombarded the Aden homsetead on Mandalore and Kyr staged his own death. When Cadden Blackthorne returned to Mandalore, Jahaal, unlike his father and his brother, remained reserved about the man's abilities and capability to rise and reclaim the title of Mandalore. He slowly began to see what they did, however, though remained skeptical that Cadden would be up to the task. Despite this, he followed Kyr's lead loyally and trusted in his vision and decisions while taking on the roles of being the public face to their resistance against Garen's reign as Mandalore.
