Septsilk was an expensive cloth used to make fine clothing. Uta S'orn and Sei Taria were known for their fondness of wearing septsilk clothing, as were the infamous Confederacy of Independent Systems scientists Ovolot Qail Uthan and Jenna Zan Arbor. Valin Draco was also known to wear scarlet robes made out of septsilk once he became an Inquisitor.
