A key visual is a promise. The world is what keeps it.

Neta Studio is an AI world builder — one sentence becomes a world with characters, places and a visual style locked in its settings. Every cover here came out of a world like that, not a blank prompt: the Hallownest ones from Hallownest, the others from their own worlds repainted in the same light.

One style, set once — The painterly dark-fantasy look lives in the world, so the tenth cover still matches the first without re-describing it.
A cast that is already there — Hallownest ships with the Knight, Hornet, the Pale King and the Dreamers; name one and the cover uses that character.
From cover to a playable scene — The same world can stage what the poster implies — a roleplay at the well, a branching scene, a short loop for the store page.

Questions, answered.

Is this official Hollow Knight art?

No. It is unofficial fan work in a Hollow Knight-style world; Team Cherry has nothing to do with it. Use it for a fan poster, a pitch deck or your own game — not as an official asset.

What exactly comes back?

One 16:9 painted cover, no text baked in. The top of the frame is kept dark and empty so you can set a title yourself.

Can I use my own character instead of the Knight?

Yes. Describe the mask, the horns, the cloak and what they carry, and the cover is built around that character. The fourth card on this page is an original vessel, not one from the game.

Can a series of covers keep the same look?

That is what the world is for. The style is fixed once, and every later cover follows it: ask for the City of Tears after the well and the palette, edges and light direction match.

Which model paints it?

The world picks one and you can name another in the chat. The detailed covers here were painted with GPT Image 2; the Hallownest world's own default is faster and flatter, which is why the first card is lighter than the rest.

Can I put a title or a logo on it?

Ask for space at the top and set the type yourself afterwards. Text the model writes into an image is unreliable and often misspelt.

How long does one cover take?

Under two minutes for the first card, second pass kept. A scene with several characters in it takes longer and usually one more pass.

Does it only work for Hollow Knight?

No. The grid has The Legend of Zelda, Goblin Slayer and Silent Hill painted in the same style. Name another world in the brief and the bug vocabulary drops away by itself.

One line in. One painted cover out.

Start in Hallownest or bring your own world — the first cover takes a couple of minutes.
