Zephyria

An Online World Built on Old-School Rules

Mountains of Ashrun · persistent online world

Download the Electron desktop client for Mac OS, Windows, or Linux. Zephyria is not played in the browser at zephyria.live — this site is the installer page. After install, you connect to the live world of Ashrun (Mountains zone): real-time multiplayer, quest chains, shops, and tabletop-inspired combat.

What you get

Combat ⚔

Old-School Tabletop Combat

Pen-and-paper combat in real time: THAC0-style attacks, armor class, saves, and spell slots that must be prepared.

World 🌐

Persistent Multiplayer World

Characters, inventory, and reputation persist. See other adventurers move and fight in the same zones via WebSocket sync.

Live ⚡

Real-Time WebSocket

Movement, combat, chat, and NPC updates stream over a dedicated Ratchet WebSocket — no page reloads or turn-based waiting.

NPCs 🧠

Living NPC AI

A server-side NPC processor gives every creature its own tick: patrol routes, dialogue, reactions, and combat decisions.

Story 📜

Quest & Story System

Branching quest chains, reputation gates, and world-state triggers — choices change dialogue and who will help you.

Classes 🎭

Classic Character Classes

Warriors, priests, rogues, and arcane casters with class kits, spell lists, and progression rooted in AD&D 1st Edition + UA/OA.

3D 🏔

3D Babylon.js World

Babylon.js renders terrain, GLB buildings, and animated characters with mesh collision, lighting, and smooth third-person camera.

Trade 💰

Economy & Crafting

Shops, loot tables, crafting, and item durability tied to classic equipment rules — gold and gear matter.

A typical session

Log in with your account and load a persistent character (stats, inventory, reputation saved on the server).
Spawn in Ashrun — explore 3D streets, plazas, shrines, and mountain passes with other players visible in real time.
Quest & talk — branching dialogue, multi-step chains, reputation gates, and world-state triggers.
Fight & cast — d20 attack rolls vs armor class, saving throws, prepared spell slots, loot, and death saves in live combat.
Trade & gear up — shops, crafting, gold, item durability, and equipment rooted in classic rules.
Log off — the shared world and your progress remain; NPCs keep simulating via the server daemon.

The world

The ancient city of Ashrun clings to the mountainside like a scar — half-buried in rock, half-open to the stars. Merchants once hawked wares from a hundred kingdoms in its plazas; now inn fires burn low, shrine prayers go unanswered, and something stirs in the passes above.

Spawn in the Mountains zone and learn the city through starter quests
Meet NPCs with schedules, dialogue branches, and reputation consequences
Explore plazas, shrines, and mountain passes in full 3D with other players online

Common questions

Can I play in the browser?: No. zephyria.live is download-only. You need the desktop client (Electron) to run the game.
Why is the installer “unverified”?: Alpha builds are not yet notarized (Mac) or Authenticode-signed (Windows). Follow the install screen steps — safe when downloaded from zephyria.live.
What happens on first launch?: The app downloads game assets (models, audio, terrain) from the live server, then connects you to Ashrun. Keep internet on until the progress bar completes.
Do I need the core rulebooks?: No purchase required to play. Rules are implemented in-game; tabletop veterans will recognize AD&D 1e style mechanics.
