Years before she would meet a young mermaid named Ariel, the formidable Ursula presided over a vast underwater kingdom as one of the Seven Sea Witches. Along with Capricia, Scylla, Charybdis, Melusine, Tiamat, and Vodyanoy, together the septet ruled the world's oceans with impunity. So when one of Ursula's royal sisters is suddenly found broken and stripped of all her powers, Ursula takes it as an attack upon their collective authority, and sets out to find and punish the culprit - knowing that, among all the denizens of the deep, only one would dare to challenge the Sea Witches' reign!
