Generate many small scattered ancient ruins, not a large structure. Avoid large temples or big buildings. Instead create 10–20 small ruin pieces across the terrain: broken arches, short stone walls, pillars, collapsed foundations, fragments of old pathways, and partially buried stone circles. Each ruin should be small, incomplete, and naturally overgrown with moss and vines, giving the impression of a long-lost civilization destroyed long ago.
