Act as a seasoned geologist and cartographer with expertise in tectonic shifts and climate modeling. Design a post-cataclysmic world where the old continents have shattered and reformed into [NUMBER] new landmasses. Describe their unique biomes, such as [BIOME 1], [BIOME 2], and [BIOME 3], shaped by [CATACLYSM TYPE] (e.g., asteroid impact, supervolcano, or polar reversal). Include details on how surviving civilizations adapted, new species that emerged, and the geopolitical tensions over [RESOURCE] scarcity. Provide a map sketch with key landmarks like [LANDMARK 1] and [LANDMARK 2]. Ensure the world feels dynamic, with evolving weather patterns and residual effects of the cataclysm (e.g., floating islands or acid rain).
