The Queen of Cups is a stewardess of the sea, the guardian of the shores where the Page and Knight walk. She is covered in seaweed, and we can imagine that she appears only at low tide. For a scepter she holds a narwhal horn, an icon of purity. In the other hand, her cup supports a squid, who can obscure and entangle when necessary.
On the positive side, the Queen of Cups offers security and inner calm. In a negative light, she can be dishonest, evasive, and undisciplined.
