The ground itself is listening.

Something vast lives beneath the surface of your world. You will never see it, only the ground it moves: a mound that crawls through grass, stone and the walls of caves, rising and falling as it follows every vibration you make.

It hears you through the earth

• Every step, jump, mined block and landing arrow sends a vibration through the ground. Stone carries it far, sand and gravel less, wool and carpets almost not at all. Leaves rustle.
• Sneak, and your steps are silent. Stand still, and you are nothing.
• When it grows wary it freezes and sends rings of ripples across the ground: it is listening. Move now, and it knows where you are.
• Hunting, it is fast. Angered to the peak, it does not stop until it reaches you, or loses you.

The Awakening

If it reaches you at the peak of its anger, the whole area around you becomes the creature. The world goes silent, the ground breathes, and you have seconds to get away before the earth swallows you.

What waits inside is yours to find out. Find its heart before the ground closes in, or the world will be left with a crater where you stood.

Things made from the creature

Survive, and you may carry a piece of it out. Its shards make tools to sense it: a seismograph whose needle points at it, a geophone that wakes your redstone when it comes near, and boots that muffle your steps.

And never, ever throw a shard on the ground.

Also

• Animals and monsters are not safe either.
• It roams the Nether too, and it is angrier there.
• Works in multiplayer (install on the server and on every client).
• Works with Sodium and Iris. A quality preset (Low / Medium / High) keeps it smooth on weaker computers.
• Everything is configurable: hearing, anger, the Awakening, the hollow, the crater, the tools.

Requires NeoForge for Minecraft 1.21.1.
