Larion World Generation Data Pack (1.21.1, 1.20.1) – Epic Fantasy Overhaul for Exploration








Larion World Generation Data Pack transforms Minecraft’s world generation into a fantasy landscape designed for exploration. It introduces massive continents, smaller islands, and unique terrain features like towering mountains, winding rivers, and climate zones. Enjoy playing this data pack!

Features:
- The world is split into large continents with plenty of smaller islands in-between. Continent sizes and shapes vary wildly.
- Temperature changes as you move north or south (z-axis).
- If you travel far enough, it wraps back around.
- Travelling east or west lets you stay in roughly the same temperature.
- “Tropical” biomes (jungle, savanna etc) generate within desert and badland regions instead of around them.
- Mountains form large “chains” roughly similar to continental plates in real life.
- They are also taller, usually between 200 and 300 blocks in height, but in rare cases even higher.
- Jagged peaks are less “jagged” than usual, shaped more like real mountains.
- World height is increased from 384 to 512
- This ensures mountains never “plateau”, even if they reach over 320 blocks.
- Build height limit is 448. Terrain doesn’t really reach this height ever (i think?) so there is always space to build.
- Terrain is more hilly than before and slopes upwards as you go further inland.
- This is completely independent of how mountainous the terrain is, so even a normal plains biome can be at Y=200 (however this is quite rare)
- Smaller biomes with less predictable shapes and placement.
- “Humidity” zones are weirder, sometimes small, sometimes large.
- Swamps and mangroves can only appear along coasts and rivers.
- Windswept terrain is more common and can appear anywhere.
- Long, winding rivers that carve though terrain.
- In low terrain they form “saddle valleys”
- In tall terrain they will keep flowing as underground rivers.
- Sometimes rivers form strange “knots” that look like lakes.
- Mushroom islands are more common, smaller and oddly shaped.
- Numerous smaller tweaks
- Dunes in desert biomes
- Less ugly cliffs at coastlines
- Less taiga in frozen zones
- More jungle in tropical zones
- Badlands mountains have plateaus instead of peaks
- Probably more..!
