Secret societies at Yale University have a long history and are associated with money, influence, and power. These societies are known for their exclusive nature, mysterious rituals, and often alums who have achieved great success in various fields. While secret societies do not always live up to their infamous reputations, they are often associated with elitism.

Hell Bent and the previous book in the series, Ninth House, present the secret societies at Yale in a fantastical way. Galaxy Stern, or Alex, is admitted to Lethe House, the society in charge of monitoring the other eight societies at Yale that engage in rituals that grant them and their former members magical abilities. While the magic the books present at the University and Lethe itself are fictional, the other secret societies of Yale are not. The three most significant are Skull and Bones, Scroll and Key, and Wolf’s Head, all appearing in the novels.

Skull and Bones, officially known as The Order of Skull and Bones, was established in 1832. Skull and Bones has counted among its members numerous prominent figures, including former US president George W. Bush, as well as influential business leaders, politicians, and academics. The activities and rituals of the society are cloaked in secrecy, which has fueled speculation and conspiracy theories.
