 * Ioulaum heads for his lair in the depths of the Northdark after abandoning his floating city as civil unrest reaches its highest levels across Netheril.


 * Netherese skyships head south to the Halruaan basin, led by the archwizard Raumark.


 * Survivors of Netheril's fall found a realm in the Underdark beneath the Wood of Sharp Teeth. The name and fate of the realm has been lost to history.


 * Karsus seizes Mystryl's powers through the casting of Karsus's Avatar, but they are too great for him to control and the Weave fails, causing Netheril's floating cities to fall to the ground. Nhalloth and Sakkors plunge into the ocean. Mystryl sacrifices herself to save the weave. But she instantly reincarnates as Mystra and changed the rules for magic users (no spell above 10th level will function). She was fast enough to save the cities Anauria, Asram, and Hlondeth, the rest of the Netheril's cities were destroyed.


 * The effects of the fall of Netheril are felt far and wide. The magical backlash from the death of Karsus causes magically supported structures in Calimport to fall, and the entire magically supported ceiling of the Sargauth Enclave collapses, covering two thirds of the city. Karsus' body falls to the east of the High Forest.


 * A large whirlpool from the surface to the mythal at Myth Nantar causes many ships to be lost and destroys many buildings in Serôs.
