"Metal Is King" - Exmortus
It's a dark and windy day. Five horsemen, each carrying a sword, and with a guitar-shaped tattoo on each of their chests, are riding toward a town. Once they reach the town, they begin slaying people left and right and pillaging the town. The cops are called in to deal with them, but they too fall by the blades of the group. Eventually, the five men come together, place their blades on top of the other blade, then raise them to the sky, leaving the ruins of the town behind.
The story shifts to a bedroom. A grandfather is with his grandson, revealing the events to be a story. The grandson asks who the men in the story were, the grandfather answers "they were the Metal Kings".
