Prompt: Create an image of a Grey Knight from the world of Warhammer 40,000, standing heroically amidst the ruins of a battlefield. The knight is clad in ornate grey armor, embellished with intricate details and symbols of his chapter. He wields a mighty Nemesis Force Sword in one hand, crackling with psychic energy, and a Storm Bolter in the other, ready to unleash a hail of bolter rounds upon any foes that dare to challenge him. His face is hidden behind a skull-faced helmet, adding to his menacing appearance. Behind him, the smoke and flames of battle rise up, while in the distance, more enemy forces can be seen approaching. The overall style should be reminiscent of Games Workshop's iconic artwork, with bold lines, vivid colors, and a dynamic, action-packed composition.
Prompt: Create an image of a Grey Knight, dressed in his grey armor and holding the severed head of a demon aloft. The knight stands in a dark, shadowy chamber, illuminated only by the eerie glow of the demon's eyes. The knight's expression is stoic and determined, as if he has just emerged victorious from a fierce battle against the forces of darkness.
