Earthfall

Earthfall was an apocalyptic historical event that occured thousands of years before the Gap on the lost planet Golarion. It took the form of a massive meteor shower that devastated the planet and caused the elves to flee through the magical aiudara gate known as the Sovyrian Stone back to Castrovel. Their migration put strain on Sovyrian as most elves prefered to remain in their homeland and were unwilling to relocate again to more distant colonies.
