The Witching centers on Elsa, a young witch seeking to find the other two to complete the trinity. As with other Vertigo books, Vankin’s story plays heavily on the idea that magic is common in the modern world (especially in the series’ setting of the U.S.), although not everyone can see it.
"…We know that her father was a famous rocket scientist working on super-secret military projects after World War II, and that he was also a self-styled sorcerer who led his own little secret occult group with many powerful and important people among its membership. He practiced sex-magick, or his rather flawed understanding of it anyway, and that’s how Elsa was conceived. In the first issue we learn that she considers her true mother not be human at all — her mother is the moon. And she desperately wants to return to her mother.
“After an elaborate, two-year ritual, she has created a way to get herself there. And she does. She flies to the moon - with great difficulty. After an unhappy lifetime of restlessness and discontent, she finally feels at home. I guess she’s looking for escapism, too, just like everybody else.
”Except that there’s a surprise waiting for her on the moon, and it’s not a pleasant one.”
