Build Your Party. Shape Your Run. Write Your Next Move.
The Return of Illunes is a turn-based roguelike RPG with a small language model built into the game. Lead a party of up to four through a branching dungeon, combine classes, skills and relics, and bring what you earn back to strengthen your next expedition.
The AI runs locally on your PC. It generates content during play without an AI server connection, subscription or per-use fee.
A New Build to Discover
Choose your route through battles, shops, rest stops and encounters. Experiment with skill and equipment combinations, weigh rewards against danger, and prepare your party for the bosses ahead.
Party tactics — Build around four base classes, their subclasses and AI-generated subclasses.
Run-changing combinations — Combine skills, gear and relics with synergies, oaths and world mutations.
Progress beyond a single run — Invest in permanent upgrades, unlock classes and grow your base between expeditions.
Put Your Idea into Words
Use Free Action to describe an attack or an attempt to help your party. The AI responds with a verdict and narration, while the game resolves successful combat actions through its attack or healing effects. Try your own wording alongside the regular battle commands.
What the AI Creates — No Two Runs Alike
Subclasses — brand-new specializations invented on the spot: name, description, stat spread, growth curve and skill leanings (within balance limits)
Skills — new techniques with their own name, form, element, power, status effects and special mechanics
Gear & Relics — unique names and lore, and which powers they carry
Bosses — entrance scenes, battle gimmicks and signature skills
Enemy techniques — enemy skills that change from fight to fight
The run's story — each expedition's premise, goal, threat and tone
Adventure events — scenes, choices and their outcomes
Free actions — type anything; the AI Game Master judges success or failure and narrates the result
Battle narration — round summaries and victory/defeat scenes
Synergies, Oaths & World Mutations — rules that reshape your run, and their stories
Shops — shop descriptions, merchant dialogue and AI-named wares
Cooking — dishes and effects born from your ingredient combinations
Companions — conversations and battle cries full of personality
Endings — an epilogue and final words written for your run alone
An AI Inside Your Adventure
Discover AI-generated skills, subclasses, equipment descriptions, enemy techniques and story text alongside the game's prepared content. The built-in model adds names, flavor and variations to your journey through Paradise.
Play at your own pace. Adjust AI content density, or turn generation off to use prepared content. Story generation can be cancelled to continue with prepared text. Generation time depends on your hardware; AI narration may sometimes be imperfect.
Descend into Paradise
In Zeta, a world of magic and machines, the Illunes sect concealed the world's secrets in a place called Paradise. Bound by a covenant with Ethelin, the last of the Illunes, you follow the trail of nine discoverers consumed by desire. What will you bring back from the depths?

AI disclosure
Pre-generated: Some 2D illustrations and the pre-recorded narration were produced with AI tools and reviewed by the developers before inclusion.Live-generated: A language model bundled with the game runs entirely on the player's device, with no internet connection. During play it writes narration, dialogue, and the names and lore of items, relics and skills; it selects among game-defined options for run content such as synergies, oaths and subclasses; and it accepts free-text actions typed by the player (for example "cut the chandelier loose"), judges them, and narrates the result. Damage, stats, difficulty, and progression are always governed by the game's own rules. Player input is filtered before it reaches the model, every generated line is checked before it is shown, and no art or audio is generated at runtime.
