Zena Antilles was a female Human who was married to Jagged Antilles and bore him two children, Wedge Antilles and Syal Antilles Fel. Together, Zena and Jag owned and ran Gus Treta, a spaceport and fueling depot situated within the Corellian sector.
Some years prior to the Battle of Yavin, Zena lost her life when criminals, attempting to evade CorSec, intentionally neglected to detach their docking clamps. The subsequent blast threatened to obliterate the majority of the spaceport. Consequently, Zena and her husband gave their lives to detach the burning tanks from the station, but they were unable to escape the resulting explosion which killed them both.
Immediately following his parents' demise, a furious Wedge Antilles hunted down the Bonestar Pirates, destroying their vessel and killing every one of them, thereby avenging his father. However, unbeknownst to them, Loka Hask, the leader of the pirates, lived through the attack.
Both of her offspring achieved widespread renown throughout the galaxy. Her son, Wedge, became a celebrated fighter pilot within the Rebel Alliance, later rising to the rank of general in the New Republic, while her daughter, Syal, achieved fame as a holodrama celebrity in the Galactic Empire.
