世界名ジェネレータ

The name of a world sets the weather for everything you build on it. Earth is quiet and familiar; Athuvia promises adventure before you've written a single map. A good world name has to sound whole — like a place with its own history, seas and skies — while staying easy to say out loud, because your players and readers will be repeating it constantly. This generator produces names for fictional worlds and realms, each with a line sketching the kind of place it suggests.

How to use it

Length sets the register. Short names (Vale, Oros, Kyth) read as blunt and elemental — good for grim or ancient worlds. Longer names (Aelendria, Saventhalor) read as lush and storied, the kind of realm with a thousand-year chronicle and several dozen kingdoms.

Complexity decides how invented the sound feels. Simple keeps names close to real-world phonetics, so they feel plausible and pronounceable. Elaborate reaches for unusual vowel and consonant combinations that mark the world as clearly not our own.

Use extra context to steer the atmosphere and genre:

• "high-fantasy realm, lush and magical"
• "harsh desert world, sun-scorched and ancient"
• "sci-fi planet, cold and clinical-sounding"
• "oceanic world, most of its surface is water"

What makes a good world name?

Coherence and singability. A world name works when its sounds hang together as if they came from one language, and when a stranger can pronounce it on the first try. The generator biases toward names that feel like a whole place rather than a random string, and you can push the tone — soft and magical, harsh and elemental, alien and cold — in the context box.

Can I name a continent, kingdom or planet with this too?

Yes. The same conventions that make a good world name apply a scale up or down, so ask for a continent, a realm, a kingdom or a planet in the context box and you'll get names pitched at that level. Generating a set at each scale is a quick way to build a consistent-sounding map.

Can I use a generated world name in my own game or novel?

Generally yes — short invented place names aren't protected by copyright, so a name the generator produces is yours to build on. Do a quick search before committing to a central one, since the model has read a lot of fantasy and science fiction and can occasionally echo a well-known setting.

Why do I sometimes get fewer names than I asked for?

World names cluster around the same pleasing sounds (Ael-, -oria, -eth), so large batches produce near-duplicates. Those are filtered out before you see them, and only the names you actually receive count against your credits.
