Drift Crashers Adventure Path Player's Guide

From the introduction:

Welcome to the Marata, your new home away from home—and your only one for a while. You never set out to be adventurers; you’re just a group of people on a job, on a journey, or doing some other mundane task. When you get thrown across the cosmos without warning, all that is shattered. You have little to no hope of an easy way out. All that drives you and your companions now is finding a way home to the Pact Worlds, even if that takes you to Hell and back. It’d be best if you didn’t have to go there, though.
