fantasy island map 3d model

In threejs on 12000x12000 grid, I need at the very south, a beach. Just a little north of that, I need tall grass grasslands and fields of flowers. To the east is a big beyond which lies an ancient city. In the center is a hill upon which a kingdom will rest. To the north the ground rises and grows barren, an ascent into the peaks. A north western mountain biome with a big lake. It looks over a dense forest that is west of the grass fields. At least 7 villages spread throughout with all unique buildings . There should at least one tavern and inn on each road, as well as in each village. In the grasslands is a massive three eyed eldritch skull thays mostly submerged. The bones of an angel wing are visible. The entire map is surrounded by mountains, but for a bottle neck through to the beach to the very south. Would you make a really beautiful gorgeous sword drive into rock hidden somewhere? And scatter jaw dropping gorgeous armor in pieces around the map.lots of plant and tree variation
