Clara Rolfe is the younger sister of Drusus Rolfe.

After her brother joined Vormund, he sent for her in Hiberia. He placed Clara in the care of an old woman named Heather Babbitt, who taught her how to make hats.

Upon returning to the city two years later, they discovered Heather had been committed to the asylum by her son and died shortly thereafter, while Clara had moved in with Kirk Callow, who allowed her to work as a hatter upstairs.
