    Fractum is a datapack for Minecraft Java Edition, aiming to enhance the base game adding entirely new biomes but also small world details, additions and features.
    The project will be costantly updated and it's totally open to suggestions and opinions about extra implementations. So my invitation is to leave a comment and follow my Reddit to take a look at the new future adds. I work on this project by my self, so if you're interested in supporting me check out my marketplace Fiverr.

    What is the objective of this datapack?
    In this new world, you will encounter not only entirely new biomes but also small additions and features: vegetation, caves, and dimension-specific decorations. This will enrich your gaming experience and make you see Minecraft's typical blocks and landscapes in a different light. But be aware that even though it's made with elements from the vanilla game, there are entirely new and unusual features. This adds an element of mystery to the game and ignites the player's curiosity and a fresh desire to explore.

    "Fractum, fragments of ideas that become reality!"
    This project is born to bring ideas to life using a game full of possibilities like Minecraft. Not just mine, but especially those of the community.[Reddit] [Instagram]

    "No limits to creativity and ambition."
    Thanks to my Fiverr gig, anyone has the opportunity to create their own datapack and thus shape any kind of idea. In this way, you can also make a small contribution to this project I've been working on alone.

    How long will it take for the datapack to be compatible with 1.21.9 that will probably add copper golems?
    The datapack looks pretty cool overall tho.

    actually there are no technical adds between these versions, so the version for 1.21.6 should be compatible
