From publisher blurb:
Don't Wait For A Countdown. Launch Right Into the Action.
We've got the crew assembled and ready. Strap into your ship and go full-burn toward adventure across the Solar System. The Expanse Roleplaying Game uses the AGE system to explore the science fiction universe created by James S. A. Corey.
The Expanse RPG Quickstart includes everything you and your friends need to play your first game except some six-sided dice and pencils: condensed rules to help you learn how to play, six pre-generated characters ready for action, and Cupbearer—a complete adventure that sends the crew on a job aboard Ganymede Station.
Cupbearer
An Expanse RPG adventure suitable for a crew of 3-6 characters, levels 1–3.
What starts out as a fairly simple job to find and recover the wayward son of a wealthy corporate family gets complicated when the crew discovers their target is involved with a powerful crime lord and devised his own way out—one that doesn't involve returning to his family.
Using the full rules in The Expanse Roleplaying Game, you can continue your adventures beyond this Quickstart mission or devise an entirely new campaign.
