        if (level == 0) {
            ChunkRandom randomChorus = new ChunkRandom(new AtomicSimpleRandom(0L));
            ChunkPos chunkPos = new ChunkPos(blockPos);
            randomChorus.setPopulationSeed(world.getSeed(), chunkPos.getStartX(), chunkPos.getStartZ());
            int islandRadius = MathHelper.ceil(islandSizeF);
            int xOffset = randomChorus.nextInt(2 * islandRadius) - islandRadius;
            int farthestZ = MathHelper.floor(Math.sqrt((islandSizeF + 1) * (islandSizeF + 1) - xOffset * xOffset));
            int zOffset = randomChorus.nextInt(2 * farthestZ) - farthestZ;
            BlockPos chorusPos = blockPos.add(xOffset, 1, zOffset);
