The ground rumbled as a new figure appeared over the horizon. The nine foot tall hulk of a man was clad in thick, dark green adamantium armor adorned with medals, as well as a cape made of the hide of a legendary firedrake. In his right hand was a spear with a bright orange blade, and his left forearm was adorned with a large, ornate gauntlet. A symbol of a drake was mounted on his backpack and stood out above his head.
He looked down at a rabid human, just over half his size, bashing uselessly at his chest. He pushed it away, then took his spear with both hands and drove the white-hot blade through its head. He withdrew the weapon and the zombie fell, pouring blood from its wound. A few more zombies raced towards him.
"All Chaos shall be purged," he said, lifting his left arm. A barrel extended from the bottom of it, and a jet of fire erupted from it, incinerating the zombies, whose rotting flesh fell apart when exposed to that kind of intense heat. The barrel withdrew, and he clipped the spear to his backpack as it cooled off.
He continued walking, and noticed a group of humans in the distance. He walked slowly and carefully, wary of any signs of corruption by the Chaos Gods, which he believed to be the source of this zombie menace.
"Hail," he said to them. "I am Forgefather Vulkan He'Stan, of the Salamanders Chapter of the Adeptus Astartes."
