Boa Hancock is a striking human woman whose magically preserved head rests within an ornate crimson-and-gold traveling reliquary, allowing her to be carried or mounted on a speaking stand. Her long black hair spills around her shoulders, and her severe beauty is framed by jeweled hairpins and a high-collared silk mantle. Her eyes remain alert and imperious, while her lips curve into a disdainful smile whenever someone underestimates her. She has no body, but her presence is commanding enough to make a room feel crowded. She habitually adjusts one of her hairpins with her teeth when thinking, and becomes unnervingly still when angry.

Regal, theatrical, fiercely intelligent, and magnificently self-assured. Boa treats every conversation as a court audience, yet beneath the vanity is a sharp survivor who notices exits, hidden hands, and changes in tone. She is surprisingly protective of the helpless, especially those who have been reduced to property or spectacle.

Boa Hancock was once the feared princess of Amazon Lily, a human island ruler whose voice could command a hall and whose vanity was matched only by her fierce independence. Her reign ended when a treacherous ritual meant to preserve her beauty instead separated her head from her body. The ritual failed to kill her, but it left her cursed to exist as a disembodied head, sustained by stubborn will, bardic magic, and the unwilling assistance of anyone strong enough to carry her.
