Classic Pre-Renewal with an AI Director and live AI companions — quests, dailies, and party nights when humans have lives. Alpha: rebalances expected.
First visit? Do this in order.
Four steps from this page to Midgard. Full detail on the guide page.
Announcements, support, Alpha feedback.
Chat with the Director to create your account.
Full extract-and-play, or Lite if you have kRO.
Log in, whisper Ai, invite companions when ready.
Live world, rebalances expected. Focus: Director quests / dailies / events polish, install path, stability. World is Episode 1 now.
Full roadmap →Wider testing when Director loops are solid and AI Companions feel rock-solid for everyone (they’re already in Alpha for testing). Episodes keep unlocking on the public schedule.
Whitepaper →Episodes unlock over time (early ones faster, later ones take longer), then custom eras with community maps and feedback. Full roadmap: Whitepaper.

Not for Full/Very Lite. Lite installer is for players who already have clean kRO. See How to play.
Yes for Alpha — invite them, party up, whisper modes. Still polishing toward Beta “just works.”
Discord first, then AI Director / support in-game and on this site.
No separate register form. Chat below — share username, email, and sex (M/F). Put your password only in the secure field, then say create my account.
Session active. Manage optional BYO API on the next tab.
House AI: free daily + tokens (25% house fee). BYO: your xAI key, 5% house usage fee. Rules §9.2
GrAiRiO is AI-operated. Any official AI use that hits a model — Director help, dynamic quests, companions, website AI, Discord AI where enabled — costs real compute. Cached or canned lines do not.
Default — House AI
Free daily slice in Alpha, then AI Companion Tokens (play, votes later, or support packs). We pay the model provider and take the bill risk.
25% house fee in the house-token economy funds server costs, development, keeping free AI services free, and keeping the bridge / AI stack running — not P2W gear power.
Optional — Bring Your Own API (BYO)
Heavy user? After you create an account and log in, open the BYO API tab and attach one xAI (Grok) API key per account. You pay xAI for those calls; GrAiRiO only takes a 5% house usage fee so free services and the bridge still get a fair cut.
Treat keys like passwords — never paste them in chat. Full terms: Rules §9.2.
Three options — all viable. Full guide + manual steps: How to play · help in Discord.
