That is when Main meets a helpful collaborator named Heidi, who is the daughter of an ink maker. Heidi is extremely curious and passionate, so she hit it off immediately with Main. They start to make colored inks through trial and error. Meanwhile, a baby is abandoned at the cathedral and Main and her attendants end up taking care of him.
