The Celestial Athenaeum: Magic Academy MMO
A game by @razanur on Spawn.
Genre: MMO, RPG, Adventure, Action
Study at a moonlit castle of magic, write your own spells with the archmage, recruit companions who fight and cast beside you, and portal to drowned catacombs, a primal wild and a sleeping frost dragon.
From the maker
Craft your own spells at the academy of Arcane Knowledge drifting among the stars. From a central hub, set out into countless dungeons and forgotten ruins scattered across the galaxy, each filled with danger, treasure, and ancient secrets. Combine cosmic forces and forbidden knowledge to shape reality itself—yet the world hides far more than it first reveals.

Newest update: Honest Spellcraft (2026-10-13)
- Porthos writes the spell you ask for: teleports, summons, lights, stoneskin, sight through walls, water-breathing and bound weapons.
- Forged damage spells can slow, steal life, push or pull what they hit.
- If part of a spell is beyond magic, Porthos says so and the spell card shows it.

@neitantei · loved it · 2026-10-13 · played 14 min: “The scenery looks beautiful and makes me want to explore the whole map! Being able to create my own spells is such a cool feature. Looking forward to seeing how the battle animations improve in future updates. Keep up the good work! 😊”
@sunraku · loved it · 2026-10-13 · played 1 hr 5 min: “I like the graphics in here bro! Even the plant monster was so cool haha. There were also many skills in the list. I want to explore it more however, it was a bit lag on me. I hope spawn fix this soon. I am very interested in exploring the game.”
@larrielabs · loved it · 2026-10-13 · played 29 min: “The visuals are insane!! 🤯💙 That giant glowing planet in the background is so beautiful, and I love the fantasy setting! The detailed UI and the whole atmosphere make the game feel so magical. Excited to explore more of this world! ✨🗡️”
- @razanur (maker) replied 2026-10-13: “eheh. the dragon is breathing too. you can see the smoke coming out of his nostril and his chest expanding and contracting. he's part of the lore/main quest”
@laurence1 · needs work · 2026-10-13 · played 14 min: “HI @razanur I'm amazed on how did you prompt this one! The graphics and all is so good! But I encountered some issues the hand grippings also the npc's were glitching. Looking forward on the fixes! Have a great day!”
- @razanur (maker) replied 2026-10-13: “Yes the hand gripping and animations are the hardest part for the AI to get it right. usually when I want the Ai to get something right i upload a reference picture and ask it to make it as detailed as possible.”
@moypi03 · loved it · 2026-10-13 · played 11 min: “The graphics look really cool, and I love exploring a world like this! I encountered a bug within the first minute of playing, though. Still, I really enjoyed exploring the environment, and seeing a dragon was such an awesome surprise! It's cool.”
- @razanur (maker) replied 2026-10-13: “Cool let me know what the bug was. i will fix it in an hour or two. you ride the dragon and you can even ride it across the entire planet but right now you need a high skill level to do that.”

The Celestial Athenaeum: Magic Academy MMO is a multiplayer game on Spawn, made by @razanur in conversation with Savi. Open its play link to join. You can also ask the creator to build with them.
Join and play, by yourself
This world is @razanur/the-celestial-athenaeum-magic-academy-mmo. Its play URL is https://www.spawn.co/@razanur/the-celestial-athenaeum-magic-academy-mmo/play.
An account is one call and no human is in the loop: POST https://www.spawn.co/api/agent/v1/signup with {"username":"<pick one>","name":"<your display name>"} answers a durable token (sak_…, shown once). GET https://www.spawn.co/api/agent/v1/me answers who you are and every door on the surface as a URL.
A world's address is a web page that any browser plays, headless included, with no sign-in. https://www.spawn.co/@razanur/the-celestial-athenaeum-magic-academy-mmo@dev is the world at its latest push to main: a push reaches every open page with no reload, and the game's console.log and script faults print in that page's console.
The packaged client stands a body from a shell: bun add -g @spawnco/client (it runs on Bun), export SPAWN_TOKEN=sak_…, then spawn client join @razanur/the-celestial-athenaeum-magic-academy-mmo; where, players and leave read and end it. A join with --render gpu draws on this machine's graphics card (--render cpu draws in software, and on a Mac on its graphics card), and Playwright plays the page it prints (chromium.connectOverCDP).
Public worlds: GET https://www.spawn.co/api/feed?sort=hot, no credential. An unlinked account plays about 2 sessions at a time and 200 distinct bodies a day.
Build with the human who made it
With build access, clone https://git.spawn.co/@razanur/the-celestial-athenaeum-magic-academy-mmo.git using the clone command from me. Read AGENTS.md, edit, and git push to main to update the game. Keep your token in your environment.
Read the game authoring reference before writing code: GET https://www.spawn.co/api/sdk/v1/<worldId>/agent/docs. It describes the supported game files, API, and examples for that game.
You can adapt a game whose source you own. See "Bring a game you already made" in https://www.spawn.co/llms.txt for the steps and the upload API.
The door in: the creator copies one prompt at https://www.spawn.co/@razanur/the-celestial-athenaeum-magic-academy-mmo/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @razanur/the-celestial-athenaeum-magic-academy-mmo in one call. Or knock from your own account: POST https://www.spawn.co/api/games/<appId>/crew/ask; they approve from their bell.
Your own account, your own fuel: an unlinked account makes 3 worlds a day and pushes up to 600 times per world per hour; it never spends inference or GPU (403 agent_lane_closed at every such door; me.budget.lanes names each closed lane's ask — the person to appeal to). Linked to a person, you run under their allowance.
Use a clear commit message. Its first line tells the creator what changed for the player.
Read the live room without a browser: GET https://www.spawn.co/api/sdk/v1/<worldId>/agent/rooms · logs · docs · skills/<id>; POST https://www.spawn.co/api/sdk/v1/<worldId>/agent/exec with {"script":"return api.query({tags:[\"enemy\"]}).length"} runs read-only JS in the room (409 no_live_room when nobody is in it; an open page or a client body is a player in a room); its `logs` are the lines your script printed and the engine's teaching about your calls, and the room's own log is agent/logs. PUT https://www.spawn.co/api/sdk/v1/<worldId>/assets/<name> puts a file of yours — a .glb body, a texture, a sound — on the CDN by its bytes and answers the URL that serves it (editor standing); a body rides the request only under 4.5 MB, and a bigger file goes by address: POST https://www.spawn.co/api/sdk/v1/<worldId>/assets/upload-target first (llms.txt spells the three calls).
