Ruen was a male human who resided in the Wreck Belt of Lotho Minor at the time of the Galactic Civil War. Shortly after the battle of Vrogas Vas, Ruen was approached by 0-0-0 and BT-1, droids working with Aphra, an acquaintance of Ruen. The droids requested repair and supplies, and Ruen agreed to help. However, Ruen discovered that 0-0-0 was programmed with the Triple-Zero personality matrix, a stolen personality matrix with a significant recovery reward. Ruen tried to apprehend the 0-0-0, but the two droids rigged his workshop to explode and killed him.
