Dawn Cataclysm

Legend
The following excerpt is from Rhyester's "Sermon of the Eclipse," written in the Year of Drifting Stars (760 DR)

Historians have tried and failed to date the Dawn Cataclysm, though most agree that it unfolded after the fall of Netheril and heralded the fall of Myth Drannor. Some say it occured before Mystra established the office of Magister some seven centuriesago, while others insist that it happened after Azuth battled Savras for supremacy in service to Mystra. Some claim it unfolded in the Year of the Hangman's Noose, when the last Chosen of Tyche died nine times in a single year within the vinelike coils of Moander's avatar. Still others believe that the recent schism in the Church of Tyche is a direct result of the former Lady Luck's corruption during the Dawn Cataclysm.
