Larion is a terrain generation mod that overhauls the style and layout of world generation in a modern-vanilla-like "epic fantasy" style favoring otherworldly, dreamlike vistas.

Larion alters the shape of the terrain, cave generation and the layout of biomes, but makes no changes to the actual biomes or their features, allowing you to pair it with any compatible biome-altering mods or just keep it close to vanilla as the screenshots show.

Please be aware that the mod is still in active development, future updates will (almost) always change how the world is generated and break continuity with previously generated terrain. I would suggest not updating the mod on existing worlds unless your are okay with weird chunk borders.

If you want a limited world size, check out the Disc World add-on datapack!

Features

• Adjusted world height, now goes from -128 to 512.
• Oceans are actual infinite oceans with landmasses of varying size. If your spawn point on a new world is on a small island, you're likely just far away from any large landmasses.
• Temperature zones are laid out vertically in bands, instead of being random blobs
• Terrain erosion (a parameter that decides between mountains, hills, flatland and windswept/swamps) is laid out very differently and can lead to unique landshapes.
• Rivers are long, meandering and form deep valleys in mountain areas. In rare cases they will tunnel straight though terrain.
• The shape of terrain is very different on the small scale too, using a special domain wrap technique to deform the horizontal axes only, replacing the janky 3d noise of vanilla. This makes cliffs way more cool looking.
• Steep hills will have exposed stone surfaces in all biomes. Somewhat steep hills get a nice gradient of stone and normal surface.

Recommended mods/datapacks

I can heavily recommend playing with Distant Horizons and pre-generating your world to allow the scale of the terrain to strike awe from the get-go.

I also recommend using William Wyther's Overhauled Overworld as a complimentary worldgen datapack as it is frankly a work of art and its visual style fits Larion perfectly. Be sure to use the datapack version, if you use WWOO as a mod you may run into issues with load order. If you find that mountains are "chopped off" at around Y=320, please open the WWOO .zip archive in for example 7zip and delete the files at these locations:

• 1-20-5-overlay/data/minecraft/dimension_type/overworld.json
• 1-21-overlay/data/minecraft/dimension_type/overworld.json
• data/minecraft/dimension_type/overworld.json

Some seeds will spawn you in water or on a tiny island in the middle of nowhere. If you want a bit more predictability when creating a world, I would recommend using World Preview.

Finally, you should stock up on worldgen optimization mods, as Larion tends to slow it down a lot due to the added complexity. Here are a few:

• C2ME (Biggest performance boost, but can be unstable)
• Noisium
• Faster Random
• FerriteCore

Compability notes with other worldgen datapacks/mods

As a rule of thumb, if mods or datapacks modify Minecraft's density functions (in worldgen/density_functions), there will be compability issues with Larion and your worlds will probably look weird in one way or the other. Basically any mod that alters terrain shape or caves is incompatible, this includes Terralith, Tectonic, Litosphere, Big Globe, Expanded Echosphere and Cascades.

However, mods and datapacks that only alter biome features and/or add new biomes should be fully compatible.
