The Sundering is a mysterious, catastrophic event by which most calendars are set at 0 A.B. Little is known about its nature; histories record that on that date, a bright purple flash followed by a persistent glow was witnessed in the eastern sky, which lingered for several hours. A series of devastating earthquakes and tsunamis followed, wiping out many of the major settlements on the continent and all but destroying most governments. The result was a Dark Age. Monster populations increased dramatically in the new power vacuum and humanity found itself having to rebuild every nation stone by stone.
The Sundering had an equally catastrophic effect on magic. Fragments from before the event indicate that magic, both divine and arcane, was once much more widespread, with entire Collegium based in modern-day Cadria and Ravenna. After the Sundering however, the presence of magic in the world faded; some mages reported feeling as though their connection to magic had been cut; others that it remained, but that magic itself was weaker. All but the best and brightest of the magi lost their magic entirely. A similar phenomenon plagued the priesthoods and caused widespread disillusionment among the faithful, who believed that the gods were either powerless or had been killed in the mysterious event. The elves, the foremost authority on arcane matters, expelled humans from El’Atol and sealed their borders for centuries in the aftermath, refusing to speak to any outsiders as to what may have happened.
The upheaval on the continent, combined with the fact that the now de-powered magi and priests were once the most loyal historians and record-keepers, caused a massive loss of history about the pre-Sundering era. Speculation about the nature of the catastrophe varies: theories include from the death of a god, the death of all gods, a magical surge, a divine battle, and a volcanic eruption. It also lead to increased speculation that there may indeed be other continents in the world to the west or east. What is known is that technology and stability are only just now reaching pre-Sundering levels.
