The Tool — what £19.99 unlocks
Every capability. From day one.
One purchase unlocks the entire toolkit — no subscription, no code, no 3D experience — then you pick a feeling and walk the world Thalyn grows around it.
Pick a feeling. Walk the world Thalyn grows around it.
You choose an emotion and the shape of the world. Thalyn resolves everything else — terrain, biomes, water, erosion, paths, assets, atmosphere, and light — into one coherent, walkable 3D world. You own the output. It is yours to keep.
No modelling. No scripting. No hunting for assets. Place what matters — a landmark, a focal point, your own imported model — and the world arranges itself around it. Change its entire look with a single pick. Walk it again. Send it to Roblox.
Change your world's entire look in a single pick.
Walk your finished world in first person, open the look selector, and choose. Every surface, texture, and object transforms at once — not a colour filter, the whole world. It happens live, in real time, and it is something no other tool can do. Every copy has it from day one.
Complete terrain generation
Heightmaps, biome propagation, natural boundaries, erosion, water bodies, paths, and designed sightlines — grown as one coherent whole, not assembled from spare parts.
Focal points
Mark a spot that matters — a landmark, an area of importance, your own imported model — and the world resolves around it, so your chosen point stays central and always reachable.
Full atmosphere
Sky, fog, time of day, and ambient mood — all driven by the feeling you chose, never a list of unrelated presets stitched on afterward.
Generation history
Every world you make is saved with its emotion and settings. Return to anything you have ever created, or grow a fresh variation from the same starting point.
Repeatable worlds
The same choices rebuild the same world. Share your choices and anyone can grow the very same world for themselves.
Roblox export
Send any world to Roblox as a complete, playable scene — terrain, assets, lighting, and atmosphere included. Export is part of the tool and free; it costs you nothing.
Included library of looks
A curated library of visual looks comes with every copy, with more to discover as you create. Ten of them are earned only through ThalynQuest — they cannot be collected any other way.
Choose the feeling. The whole world follows.
Serene
Open, gentle, unhurried. Spaces that invite you to rest.
Joyful
Bright, abundant, generous. Worlds that feel alive and welcoming.
Oppressive
Weight and enclosure. A world that closes around you.
Desolate
Emptied. The feeling of something that was, and is no longer.
Eerie
Wrongness at the edge of perception. The unseen that shouldn't be there.
Chaotic
Overwhelm as terrain. A world that refuses to resolve.
Named for the Celtic word for poetic inspiration, Awen is the in-app credit used to generate worlds — and every copy starts with a generous grant.
A treasure hunt woven into your worlds.
ThalynQuest is a free, optional treasure hunt threaded through Thalyn. Read the riddles, shape the worlds they describe, and find the relics hidden inside your creations. Claim them to earn rewards money can never buy.
Those rewards include new powers — floating sky-island worlds, blending more than one emotion into a single world, and custom audio environments — alongside ten looks that can only be earned, never bought.
The toolkit is complete with or without it. The quest is simply more to discover once you are ready.
Building sky-island worlds is a quest reward. Walking through a sky world someone else made is always free.From ancient song, all worlds are born. Yours is next.
Available on Steam · PC · £19.99 · one-time · Early Access
