Comics legend Grant Morrison introduces us to an old friend, Santa Claus, as we've never seen him before.

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 origin story of Santa Claus. It’s 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, The Multiversity) and artist Dan Mora (Hexed) revamp, reinvent, and re-imagine 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 finally answers the burning question: what does Santa Claus do on the other 364 days a year?
