In a few million years our solar system will be uninhabitable. Earth will have suffered any number of calamities, both natural and man made. In 1 billion years our sun will begin to die, expanding and consuming the terrestrial planets and reducing Mars and Earth to barren cinders. A few billion years after that, our galaxy will collide with the Andromeda galaxy. And one trillion years from now the entire universe will begin to die as every star burns through its fuel and all light is extinguished.

We cannot survive here. For humanity to continue we will need to leave our solar system, our galaxy, and eventually this universe.

One Trillion Years is a roleplaying game about humanity’s survival. You create a human diaspora, a collection of people who have left Earth in an effort to survive as the universe disintegrates. You’ll lead them through trillions of years of space and time, play star-faring guilds as they address different obstacles, and inhabit your own characters from the far future.

  • Players: 1-4
