Impact from a sufficiently large asteroid would be powerful enough to wipe out a region or destroy a planet, but smaller-scale impact events, like from a meteor shower, present hazards that could be survived. This shower might arise naturally, or it might be the result of the PCs or other forces preventing a greater calamity by breaking a world-rending asteroid into smaller pieces.
