Trivia

 * Mab is based on the character of the same name from the poem "Queen Mab" and also serves as an allusion to Morgan le Fey from the original Arthurian novel.
 * Ironically, her sister, Vivienne conceived a child with Merlin in order to make use of his magic, just like how Mab attempted to use Merlin's magic to bring people back to Paganism.
