Cantorite is the world the games are set in: a nine-world star system, a crystal that secretly does something nobody planned, and the factions that fight over it. The games are different ways into the same story.
Each game runs on its own site. One Cantorite account signs you in to all of them.
Three factions strip-mine a crystal that is secretly someone else's harvest. The louder you mine, the sooner the reapers come. Real-time strategy that runs in your browser on desktop, tablet and phone.
You are a freelancer in the Vesper Reach. The Directorate pays, the Umbra pays, the Free Holds pay when they can. Every crystal you cut is a note the Harrow can hear. Work loud enough and the reapers come for you.
The canon is the shared story. The achievements and leaderboards collect what you do across the games.
