Deeper underground

A Vision for Minecraft’s Underground Future As a lifelong fan of Minecraft, I’ve always loved the thrill of digging deep, uncovering secrets, and getting lost in the vast underground. But after the Caves & Cliffs update, I believe we’ve only scratched the surface literally. Why Stop at -64? The current world depth ends at Y=-64, but what if we could go deeper? Imagine descending into primordial layers, where the world grows darker, stranger, and more dangerous. A place where even the Warden dares not tread. We dwarves, those of us who live to mine need more depth. We want to feel small in a massive, mysterious world. We want to get lost in the dark, to feel the thrill of discovery again. New Underground Biomes & Structures Let’s bring life and death to the deep. Glowing Mushroom Biomes Bioluminescent fungi, and fungal mobs. Frozen Caverns Underground ice biomes with frostbitten mobs, and ancient frost ruins. Sunken Abyssal Oceans: Deep ocean trenches that plunge below -64, giving purpose to the Nautilus Mount and its Breath of the Nautilus effect. Ancient Catacombs & Collapsed Mineshafts: More than just wooden beams, think labyrinthine ruins, cursed miners, and forgotten machines. What We’re Asking For Extend the underground beyond -64 into Deeper Realms. Introduce new underground biomes and diverse structures. Give players a reason to explore again—to fear the dark, to seek the unknown, and to uncover the forgotten.

    “Deeper Realms” – A Vision for Minecraft’s Underground Future

    Minecraft’s underground is due for a deeper, darker evolution. After Caves & Cliffs, we’ve only scratched the surface. Why stop at Y=-64? Imagine descending into ancient layers where even the Warden fears to tread.

    We want to feel small in a massive world. We want to get lost. We want to diggy diggy hole.

    New Biomes & Structures:

    Glowing Mushroom Caves: Bioluminescent fungi and spore clouds.
    Frozen Caverns: Ice terrain, frostbitten mobs, ancient ruins.
    Magma Sanctums: Lava rivers, basalt spires, fire-themed enemies.
    Abyssal Oceans: Deep trenches for the Nautilus Mount and “Breath of the Nautilus.”
    Catacombs & Collapsed Mineshafts: Labyrinthine ruins, cursed miners, forgotten machines.
    The Lore Is Already There:

    Reinforced Deepslate portal frame—indestructible, unused, shaped like a portal.
    Disc 5 and “Otherside” hint at portal activation and void echoes.
    Echoing Void DLC introduced Endersents, void corruption, and End bosses.
    What We’re Asking For:

    Extend depth beyond -64.
    Add new underground biomes and structures.
    Connect the Deep Dark, End, and Void into a unified experience.
    Let’s make Minecraft deeper, scarier, and more mysterious. The underground should be as infinite and awe-inspiring as the stars above

    I love this idea would there be mini-bosses or something down there and secrets like in some structures above ground? Also, the glowing mushroom biomes, would they have new vegetation and plant life? I think the underground needs more of that kind of things.

    Yes there would/could be be mini bosses, an actual boss or two. And yes definitely more vegetation and plant life ! And most likely more secrets in possibly bigger underground structures.
