Jasper

Jasper is the treasurer of the Tailors' Guild in Fitzburg and the main antagonist in the story of Invisible Seams.
He acts as the Guild leader's right hand man, but is particularly intent on keeping dressmakers of low standing from joining the Guild, including the protagonist Moth. He has a generally snobby and entitled attitude, and he doesn't shy away from bullying, sabotage and physical violence to pursue his goals.
