She enjoys modern fashions and parties, frequently using her glamour to command attention in patriarchal social settings.

Francis is Florence's son and the youngest member of the Doyle family currently living at the estate.

The vigorous, handsome heir to the Doyle estate who recently married Catalina. He presents an arrogant demeanor and casually dismisses concerns about his wife's deteriorating health.

Noemí's cousin and Virgil's newlywed wife. Once a romantic who loved fairy tales and dreamed of a glamorous life, she is now isolated in the moldy rooms of High Place.

She reportedly shot several family members before turning the gun on herself to avoid a forced marriage to her cousin. Her history serves as a grim warning of what happens to women who rebel against the family structure.
