GATHER AT THE HEARTH
Your world.
Your party.
One host, up to four guests. A private invitation is all that stands between separate roads and a shared adventure.
- 01
Light the hearth
Open a saved world in Solaria and choose Co-op. Start a hub-backed session explicitly. Your device runs and saves the world; keep the game open.
- 02
Send the invitation
Copy your ten-character invite code from the game. Send it privately to your friends. Replace or close an invitation from the host’s lobby when plans change.
- 03
Cross together
Guests open Join Co-op in the game and enter the code. The hub routes your connection; the host validates your actions. Use the same compatible game release.
Before you set out
The host holds the world
The hub is a connection service, not a dedicated game simulator or cloud save. If the host leaves or suspends their device, the session stops.
Private codes, honest boundaries
Deployed HTTPS/WSS encrypts each connection to the hub. Relay traffic is not end-to-end encrypted from the server operator. Share codes only with people you trust.
