Parallel lives is the Triumvene ongoing world. Designed as a place where updates to politics, global events, and campaign materials live, it lets all the players of Triumvene around the world play in the same universe, affected by the same events, and with the ability for groups to directly influence the evolution of the shared universe.
The Original Campaign
There was also a standalone campaign created specifically for The Imperial System, in the Triumvene setting, written for the original book published back in 2019. It's called The Ghosts, and you can find it here.
There's also a small group of role play exercises to help you and your group hone your improv skills, which you can view below.
