Hear an NPC answer

01 — Live dialogue

THE WORLD ANSWERS

Ask what you like. The reply is written and voiced while you wait. This exchange is replaying a real session, at real speed.

You

“Who burned the longhouse?”

YLVA · SKALD

“Ash still warm on the beams. Riders with no banner, at the hour the dogs went quiet.”

RESPONSE 1.84 S · VOICE SYNTHESISED · MEMORY 7 TURNS

None of these lines were written in advance. Each reply is generated from the state of the world and the NPC’s own memory, then voiced by speech synthesis.

02 — Generated quests

Errands nobody scripted

The world reads its own state and writes you an objective for it. A ferryman who drowned last night, a feud that started while you were away.

03 — Combat

Weight before speed

Melee built on an ability system, dodges that commit you, enemies that hunt by sight and by sound. Every swing costs something.

04 — Survival

The cold keeps a ledger

Hunger, thirst, health and rest. Food, fire and sleep are decisions you make in the open, not entries in a menu.

05 — Under the hood

HOW THE VOICES WORK

1.84 s

median end-to-end, question to first audio. Target under 3 s.

7 turns

of conversation each NPC keeps, and carries between meetings.

3 voices

personalities in the beta build, each with its own voice and manner.

UE 5.4

Unreal Engine 5.4, Gameplay Ability System, semi-open world.

The pipeline

The game sends the world’s current state and your history with the NPC to a cloud backend. A language model writes the reply; speech synthesis voices it. Text and audio stream back together, so the NPC starts speaking before the sentence is finished.

Quests

The same service writes objectives. It reads what has happened in the region, who is alive, what you already did, and returns a quest with its own text and conditions. Nothing is drawn from a fixed list.
