This LORA is a style for background.

Forgotten Dungeon, medieval stone prison cell deep beneath an ancient fortress, rough weathered masonry walls and vaulted stone architecture, heavy iron barred door recessed in an arched doorway, short worn stone steps leading to the entrance, thick rusted chains hanging from wall-mounted iron rings, massive stone sleeping platform covered with aged coarse fabric and tattered blanket, scattered straw across cracked flagstone floor, exposed wooden ceiling beams, warm lantern suspended from the wall casting golden amber light, dramatic chiaroscuro illumination, soft shadows, atmospheric dust, damp cold underground environment, realistic textures, historical dungeon interior, cinematic composition, ultra-detailed stonework, moody medieval ambience, abandoned confinement chamber, high realism, volumetric light glow, dark corners fading into shadow.

I created datasets images with AI (ChatGTP) based on my own prompt. LORA was created with fluxgym (RTX-4090).
