 * In Chondath's bitter civil war, necromantic magic is wielded in battle on the Fields of Nun. This leads to a plague that decimates the country, giving the conflict the name "the Rotting War".
 * Raiders from the city of Phlan attack Zhentilar soldiers, causing Zhentil Keep to act to defend itself.
 * Melvaunt comes to Phlan's aid against the forces of Zhentil Keep and drives off its forces. Zhentil Keep declares war against both cities.


 * The Rotting War causes Chondath to fracture into loosely allied city-states.
 * Chondath renounces its claims on the Sembian city-states of Chondathan and Chauncelgaunt, which become independent.
 * Under the cover of the Rotting War, Ormpetarr finally manages to secede from Chondath, having failed six times before.
 * Tchazzar becomes the Sceptenar of Cimbar, then begins to extend his power along the coast, of what is then northwestern Unther.


 * Sammaster's research into necromancy results in the Cult of the Dragons' first successful creation of a dracolich, Shargrailar. The rituals and components required are recorded in the Tome of the Dragon, which becomes a holy relic for future Cult cells.
