-10000 DR


 * Corellon Larethian, acting through his priests and High Mages, magically transforms all dark elves into drow, both the corrupt Ilythiiri and others.
 * Three months later, the Seldarine summon elves to the place later known as the Elven Court. There they mediate disputes and restore peace between the elven nations.


 * Descent of the Drow: Within two months after the change, all drow retreat into the Underdark.


 * The dark elves of Narathmault are similarly transformed, and this act breaks their bindings over their army of fiends. The fiends revolt, and the drow, led by Undrek of Clan Sethomiir, together with their minotaur servants, flee into the caverns beneath the Plateau of Thay.
