Create a realistic abstract fantasy landscape of a medieval city

Create a realistic abstract fantasy landscape of a medieval city. The scene is dark and mysterious, with a predominance of dark shades and deep reds. Streams of blood flow through the streets, with organs scattered around and piles of bodies, primarily humanoid creatures, lying about. The city is marked with scorch marks and dark, blood-red fires raging under a dark sky. The only source of light is a shattered, ashy dark moon, casting an eerie glow over the landscape. Thick, red blood rains down from the sky, adding to the grim atmosphere.
