Square Hammer

The music video was directed by Zev Deans and stars Brendan McGowan as Cardinal Copia, Papa Emeritus III, and himself. It was filmed in Brooklyn, New York.

The camera travels through a green-lit city during a lightning storm. Papa Emeritus III takes a paper from a hawker. He reads about a Mysterious Spectre who has seized power. He also reads about his role in the first ever moving picture. The picture "Square Hammer" is set to premiere at the Meliora Grand that very night. He exits the limo and waves to his fans. He and his Nameless Ghouls enter the theatre. They greet fans and take their seats in the front row.

The silent film starts with a man holding a torch amidst a dark and stormy landscape, also during a lightning storm. He finds a tunnel. A portcullis raises, revealing Papa Emeritus III as a mysterious spectre. He conducts the man inside, showing him a stone coffin, which starts to open, revealing more lightning within. Back in the theatre, Papa Emeritus III appears surprised about this part and the projector starts to spark. In the film, a squared hammer surrounded by electric arcs is revealed. The intertitle refers to it as the "Square Hammer". The man picks it up as the mysterious spectre makes mystic passes. The Hammer glows and emits lightning, and the mysterious spectre's left eye glows.

Suddenly, the mysterious spectre puts his hand through the screen. It arcs with power. Papa Emeritus III sees it, but the others appear unconcerned. Then the mysterious spectre bows and becomes a cloud of bats, which chase everyone except Papa Emeritus III and the ghouls outside the theatre. An afterimage of the mysterious spectre glows blue on the screen.

Outside, the bats ascend into the night sky and congeal into a giant spectre, silhouetted against the full moon. Inside the theatre, the projector sparks even more violently and shows an image of a red cardinal on top of a cross before the film melts. Papa Emeritus III has had enough and leaves. Outside, the blue image of the spectre glows against the sky. A spotlight passes over it and its left eye glows. Papa Emeritus III's left eye begins to glow before the cut.
