I’m creating a world based on the book fourth wing with basgiath and all the quadrants. I need a Minecraft seed that has this layout, spawn in large FLAT plains biome with preferably no trees. And directly beside that I need a large ROUND mountain or PLATEU plains biome that seems like an island with a river going all the way around it, that’s about 30 blocks higher than the flat plains biome. It would also have to have enough room at the bottom of the mountain for me to add a dark oak forest biome for the “threshing” section. On the other side of this mountain style plains biome, there would need to be another mountain connected to it with a flat top but that’s about 50 blocks higher than the other mountain
