Aylmer is an 18th-century scientist who is committed to his work. Aylmer’s entire life has been about figuring out the way that nature works. He recently married Georgiana.
Georgiana is distinctive in that she has a minuscule red birthmark on her cheek in the shape of a diminutive hand. Most men who pursued her found the birthmark attractive; some catty women said that it messed up an otherwise perfect face. Georgiana has always liked it, until Aylmer brings up the topic one day soon after their marriage.
