the shattered realms

concept: a mysterious event has caused the over world to crack open new mini dimensions each one tied to a unique biome. these aren’t full dimensions like the Nether or End—they’re small “pocket worlds” that offer rare resources, mobs, and secrets tied to their biome type. example of biome-dimensions: crimson grove (from forests): a glowing red forest floating in twilight, with spirit foxes and ancient wooden ruins. glacier hollow (from snowy biomes): a frozen cave dimension with slippery terrain, ice spirits, and frost ores. sandrift depths (from deserts): an underground real beneath the sand filled with glowing crystals, sandstone golems, and shifting mazes. skyroot peaks (from mountains): a floating sky island world with bouncing cloud mobs and rare sky wood trees. how to enter: find special biome altars in the over world (rare structure). place a biome core (crafted from rare materials found in that biome) to open a portal to its pocket dimension.
