The Krass family was an Imperial human family that lived during the Galactic Civil War. It consisted of Romwell Krass Junior, his father Romwell Krass Senior, his wife Yileen, and his son Qarwell. Romwell Junior lost his family during a New Republic attack on the Hyborean Moon following the Battle of Endor. Romwell survived and traveled throughout the galaxy grieving for his family. Krass later attacked a New Republic starfighter pilot on Takodana before being stopped by Maz Kanata, who urged him to make peace with the past.
