"In the early 22nd century, a colony ship set out from Earth, bound for a nearby star system with a recently discovered Earth-like planet. When the Adventure arrived, the first crew-members out of suspended animation were quick to notice that, although the planet is approximately 25% larger than Earth, the gravity is within a few percentage points of Earth-normal. This mystery*, however, quickly took a backseat as catastrophe struck the vessel. A string of critical malfunctions caused the Adventure to begin sinking slowly towards the planet. Working quickly, the crew managed to bring it to more-or-less intact landing on the surface – but not before several chunks of the population had taken to the escape pods and rocketed off for parts unknown. Several generations later, a wide section of the continent upon which the Adventure landed has been mostly settled (centered on the crash site itself, which has become the location of the colonists' main city), and the Adventurers (for so the colonists call themselves) can afford some time from the business of surviving on this new world to searching for their lost kin."
