Dealk was a male Human captain who served the Galactic Republic during the Galactic War against the resurgent Sith Empire. Stationed on Balmorra in 3642 BBY, he led a group of soldiers to retake the Balmorran Arms Factory from the Empire. Unfortunately, the soldiers were unaware of the Neutralizer, a prototype Imperial weapon that disabled standard Republic weaponry. Left defenseless, Dealk lost a quarter of his men before being forced to retreat to Upper Sundari Outpost.
