Abdan-Sho was a Voss commando who lived during the Galactic War between the Galactic Republic and the Sith Empire. In 3641 BBY Abdan-Sho and the Republic scout Kelnu Velus surveyed the Gormak fortifications on the Fest Our Island north of the Nightmare Lands. They asked a Republic-aligned individual to retrieve experimental powered armor from the Gormak and destroy the power stations used to make it.
