Six

During her incarceration at the Ivory Forest Glassworks, Thessa Foleer labels the other prisoner siliceers there by their workstations. She labels a man in his early thirties "Six." He has brown eyes, broad shoulders, and lots of siliceer scars.
STORY
Six tries to blackmail Thessa Foleer into filling his godglass quota, like she was doing for Axio Darnasus, threatening to tell Craftsman Magna that Axio can't make godglass. Before he can finish his threats, Thessa strikes him across the face with her shears before threatening him back with a future "accident" should anything happen to Axio. Six then backs off.
