Truman is a metropolitan world overseen by an Engine of the same name.
There's never a shortage of activities to do on Truman. From solving global crises to keeping the floors cleaned, Truman tracks everything and assigns it to whoever is willing and qualified to take it — for compensation, of course.
Outsiders are welcome, but the frenetic, ever-busy nature of the planet tends to scare off most.
When the great silence came, it was Truman who kept our world afloat, kept us alive, and gave our lives meaning. It knows better than anyone else, especially you.
