SourceForge's Stellation development page. Stellation is open source. If you want to see how it works, want to set up your own Stellation server, or feel like fixing something you think is broken, this is the place to go. Stellation uses the LambdaMOO VM as its core run-time system. Mobile units are comprised of things like cargo ships, jumpships, warships, and so on.
Stationary units are things like factories, refineries, and buoys.
Stationary units can be either built on-site or else built elsewhere and then towed by a tug. Speed of light constraints mean, of course, that you can only communicate with one of your units if there's an FTL transceiver nearby. These transceivers are housed in special units called jumpships . These ships will be crucial to your campaign. Which brings us to a major point.
