A beautiful woman of Caribbean descent, Calypso is a talented singer and dancer. She tells stories of faraway places to the children who visit the Midnight Circus. She doesn't limit her activities to the Renaissance Fair. Seemingly benign, she is really Unseelie in outlook and is the Summer King's constant companion; encouraging him in his crueler activities. A petty plotter, she unrealistically dreams of taking Astarte's place in the Infernal Trinity, and may aid those she thinks have a chance of harming the Autumn Queen.
