A Voice-First Fantasy Mystery · Powered by Local AI

Eruin

Everyone Has Forgotten. Including You.

Wake without a name in a town stripped of its memories. Speak naturally to its inhabitants, unravel the spell, and discover why this forgotten kingdom seems to know you.

A spell took every memory in town. Yours included.

No name, no past, no explanation — only a walled town of strangers who seem to know you. Ask the right questions, and the past starts answering back.

Speak, Don't Select

Characters that listen,
remember, and talk back

Key characters are driven by local AI — each with their own personality, knowledge, and memory of you. Talk with your real voice or type, in your own words. No dialogue wheel, no picking from a list.

And conversations stay in the world. Nothing pauses: move around, interrupt, hesitate, or walk away mid-sentence — and characters can react to that. What you say — promises, contradictions, how you treat them — shapes relationships, quest progress, and what comes next.

Your voice
"Alder sent me. He said you could prove I belong here."
Alder says many things when he wants someone else to solve his problems. Very well — answer my riddle, and we shall see where you belong.
The world reacts
◇ Morrin remembers: Alder sent you ◇ Disposition: Wary → Amused ◇ The trial begins

From Act 1 of the demo. Morrin's replies are AI-driven; her trial is authored by hand.

Core Pillars

What makes Eruin different

I

Speak, Don't Select

Talk naturally using your microphone, or type if you prefer. AI-driven characters understand your own words — no dialogue wheel forcing your hand.

II

Conversations Stay in the World

Dialogue never locks you into a menu. Move around, interrupt, hesitate, or simply walk away while someone is talking — and characters can react to that.

III

Your Words Have Consequences

Characters remember important interactions — promises, contradictions, how you treated them. What you say shapes relationships, quest progress, and what doors open for you.

IV

Restore What Was Forgotten

The town has lost its memories. Question its inhabitants, notice what doesn't add up, and recover fragments of the past to understand the spell — and your connection to the kingdom.

V

Handcrafted Story, Living Dialogue

The world, characters, mystery, trials, and consequences are authored by hand. Local AI lets key characters understand your words and respond within the designed story.

VI

Private and Local

Speech recognition, AI dialogue, and character voices run locally on your computer. No cloud processing, no account, no subscription.

One conversation. A chain of consequence.

Step One
You speak in your own words
Step Two
The character understands & remembers
Step Three
Relationships & quests move forward
The player stands at the edge of a dark lake beneath a storm-lit purple sky
No Dead Ends

Failure is still gameplay

Fail Morrin's trial and she may turn you into a frog. That is not a game over — it is the beginning of another playable sequence, down at the lake below her woods.

When you find your way back, you can try a different approach. In Eruin, a conversation gone wrong changes the adventure instead of ending it.

Glimpses of Eruin

The player stands on a lantern-lit forest road beneath a churning purple storm
The forest road, where a witch named Morrin is said to dwell
A traveler approaches the fortified town gates under a violet sky
The gates of the town, where Alder decides who may enter
Lantern-topped towers line the brick wall of the town at dusk
Lantern towers along the wall, keeping watch over the forgetting
The player wakes on a night-time forest path as a glowing wisp hovers beside a carved tree
Waking without a name, the Guiding Light hovering close by
The player stands in a grassy meadow by a lakeshore beneath a magenta sky
The meadow by the lake, quiet in the storm's strange light
Forgive me, stranger. I cannot tell you my own mother's name, let alone yours. And yet your face... I feel I ought to know it.
