Make a biome with its own mood
Describe a landscape — a glowing mushroom grove, a crimson desert, a frozen tundra — and the engine writes a valid custom biome: its own grass and water colors, climate, and fog. It slots into worldgen as pure datapack data.

Questions people ask
Why don't I see it in my current area?
Biomes appear in newly-generated chunks. Explore outward or start a fresh world to find it.
Can I put it in its own dimension?
Yes — the dimension maker builds a realm with a custom biome baked in.
Is the biome data valid?
Always — it's generated from validated templates with the correct format for your version.
Why it never breaks
No language model writes these files. Deterministic engines parse your description into validated parameters and emit game files that are correct by construction — then CI boots real Paper and Bedrock servers weekly to prove packs still load on current Minecraft.
