4-Player Party · Live Boss Raids

FEATURED

Four players swarming a dungeon boss: live positioning, focus fire and damage numbers filling the sky — tank, damage, healer and support each doing their job. This is where an MMORPG gets good.

Holy Capital · Players Everywhere

The capital never sleeps: crowds of players, world and region chat scrolling nonstop, parties forming and stalls trading. You can play alone — it’s just better together.

Guild Territory · Where Members Gather

A private 2D territory for every guild — members gather, hang out and set off together. The hall upgrades stage by stage into a Hall of Glory as the guild grows.

Auto Battle · Keeps Fighting Offline

The server takes over targeting, skills, potions and death handling; your quota accrues even after you close the tab. Less chore, more reward when you come back.

Mining, logging, herbalism and fishing live in the same fields as the monsters, and materials flow into the player market — non-combat players get a stage of their own.

Forsaken Land

The world boss deep in the Forsaken Land. Every player on the server fights it on the same map — join straight from any channel, and your personal contribution decides your share of the rewards.

  • Coalesced from the remains of fallen gods, it still wanders the land no one claims.
  • Server-wide battle: everyone present joins the same fight — no party, no sign-up.
  • Dense status effects and AoE; personal damage, positioning and revives are all tallied.

FAQ

Before you start, a few quick answers

Do I need to download or install anything?

No. Play directly in a mainstream browser on PC, Mac, Android or iOS. You can also add it to your home screen and launch it like an app.

Is it free? Do I need an invite code?

The base game is free to play and no invite code is required. Sign in with Google, Discord, LINE or an account password to begin.

Is this an idle browser MMORPG?

Yes. Auto battle and offline progression keep your character earning experience, gold and drops when you are busy. When you return, 4-player dungeons, world bosses, guilds, trading and character progression keep the multiplayer MMORPG experience deep.

Can I play on mobile?

Yes. The live version supports mainstream Android and iOS browsers as well as PC and Mac.

Can I install it to my phone like an app, and what happens offline?

Yes. Open the game in your mobile browser and choose "Add to Home Screen" — you get a desktop icon that launches full-screen and plays like an app, with no app store and almost no storage used (technically a PWA). Auto-battle also keeps accruing quota while you are offline, so you collect the rewards next time you log in. See the install guide for step-by-step setup.

How is it different from a classic MMORPG?

No download, cross-device, click-and-play. The depth stays: four classes, talents and advancements, dungeons and world bosses, guild social — without a giant client.
