A Warhammer 40k Sister Of

A Warhammer 40k Sister of Battle, with red braided hair and freckles, sits on ancient stone steps, eating a chocolate bar. She wears crimson power armor, a backpack with a spiked mace, and holds a bolter rifle. The scene is a ruined gothic cathedral in a desolate, war-torn landscape under heavy rain. The art style is a gritty, comic book illustration with strong black outlines and watercolor-like shading. The lighting is dim and diffused by the stormy sky, creating a somber, melancholic mood. Colors are desaturated, dominated by dark blues, grays, and browns, with pops of deep red from the armor. Torn banners hang from crumbling arches in the background. Rain streaks fill the frame, impacting puddles on the ground.
