The smash-hit series by legendary creator Grant Morrison and phenom artist Dan Mora exploring the secret origins of the world’s first superhero, Santa Claus.

He’s a myth. He’s a legend. He’s loved worldwide by children and adults alike...but does anyone truly know the origins of Santa Claus? Set in a dark fantastic past of myth and magic, Klaus tells the story of how Santa Claus really came to be—the tale of one man and his wolf against a totalitarian state and the ancient evil that sustains it.

Award-winning author Grant Morrison (All-Star Superman, Happy!) and Eisner Award-nominated illustrator Dan Mora (Go Go Power Rangers, Hexed) revamp, reinvent, and reimagine a classic superhero for the 21st century, drawing on Santa’s roots in Viking lore and Siberian shamanism, and taking in the creepier side of Christmas with characters like the sinister Krampus. Klaus is “Santa Claus: Year One” and finally answers the burning question: what does Santa Claus do on the other 364 days a year?
