Jagged, more commonly known as Jag, is the third son of Baron Soontir Fel and a famous actress named Syal Antilles, Wegde Antilles' older sister. He followed his father, and two older siblings, Davin and Cherith, in becoming a member of the Chiss Expansionary Defense Force. He became the top of his class, becoming flight, then squadron and finally wing leader of the deadly Chiss fighter wing, Spike.
His mother was presumed dead on the death of her parents though it has been assumed that she was taken care of by Grand Admiral Thrawn who sent her into Chiss space to keep her safe from Ysanne Isard. This care may also be to keep the champion fighter pilot, Baron Fel loyal to Thrawn and it worked as he even offered himself for the cloning experiments.
Jagged is presumably named after his grandfather Jagged Antillies also has a sibling in the Chiss Phalanx House. His first appearance in Republic space, though he finds it hard not to call them Rebels, was at Garqui and the fight to repel Yuuzhan Vong attack on Ralroost. He also helped in the defense of Ithor and he sent one squadron home and helped the Rupublic with the Yuuzhan Vong attack at Kalarbra and Rodia, but were recalled soon after the fight at Ithor because he felt that his squadrons were making much of a difference.
He latter returned to Chiss space only to be sent on a scouting mission back into New Republic space with Shawnkyr Nuruodo to discover how to defeat the Yuuzhan Vong at his father's command. He traveled to Hapes (Vanguard) he and his wing mate escorts Jaina Solo's Yuuzhan Vong ship Trickster into Hapes and takes Kyp Durron as part of his squadron. He has several encounters with Jaina Solo, they "share evasive maneuvers" on the Hapes dance floor. He starts up a new squadron of Hapes pilots and leaves Shawnkyr in charge as he joins Jaina's Twin Suns Squadron with Kyp Durron. They three make a formidable trio in the battle field, destroying skips with ease and inventing a new missile attack with the force.
Towards the end of Rebel Dream Jaina and Jag express their feelings for one another.
Later Jag is reassigned to his own squadron of Chiss pilots and is sent to stop Yuuzhan Vong traps allow the Hydian Way on one such occasion he "bumps" into Han and Leia and stops to have a brief chat about the Imperials. He is in constant holo contact with Jaina.
