RGC, Ruined Gothic Cathedral, rgc_floor, cracked stone floor composed of large irregular slabs with deep seams and uneven joints, heavily worn surface with chipped edges, erosion and granular texture, dark damp patches creating subtle reflective sheen, scattered debris and fine dust embedded between stones, smeared and pooled dark dried blood stains following natural cracks and surface depressions, organic irregular patterns with glossy wet highlights contrasting matte stone, perspective stretching into distance with shallow depth of field, foreground sharply detailed while background fades into soft blur, surrounding collapsed rubble and broken masonry lining edges, towering gothic columns rising out of focus, diffused cold daylight filtering through distant windows creating soft volumetric haze, muted earthy tones with desaturated palette, high texture fidelity, atmospheric decay
