Ygal Delois was a dark-haired Calian male who served as a member of the Calian Confederacy and a protégé to Aron Peacebringer in the capital city of Illyriaqüm on the planet, Shiva IV. Soon after the Battle of Hoth, Imperial forces led by General Sk'ar, landed on Shiva IV and established a power base there. Delois knew that Sk'ar’s forces were of a greater strength then that of his own people, and so he betrayed the Calian Conderacy and joined the Empire. Delois kept his actions secret from Aron Peacebringer.
