Create a skyblock floating island archipelago with 1 large central hub island and 8 smaller surrounding islands. Only generate island foundations, not a finished base. Every island must have a flat buildable top plateau, bridge-ready edges facing the center, and a dramatic rocky floating underside. Use a limited neutral palette: stone, cobblestone, andesite, tuff, stone bricks, dirt, grass, coarse dirt. No buildings, no towers, no monuments, no machines, no trees, no water, no detailed decoration, no rare blocks, no ores, no netherite, no terracotta, no concrete. Focus only on premium floating island socles for a modded skyblock mega-base.
