Madame Vulture was described as "The Sea Queen" and appears to have been the leader of a band of pirates. She and her men hid out in a large, slimy, rat infested castle on cliffs overlooking the sea. The castle was filled with traps and hidden passages and there were hidden stairs leading to a sea cave. Madame Vulture was rather unfriendly to anyone who came near her castle, and this brought her into conflict with Dart Daring.
